Seth presents a theory that is commonly debated: Is it really possible for bacteria from a flushing toilet to reach a toothbrush sitting on a bathroom counter 6 feet away? Our experiment puts the urban legend to rest once and for all (hint: the results are disturbing). Later, Tom challenges Seth and Michael to test a theory that is easier said than done: Will any of them be able to achieve the seemingly simple charge of eating six saltine crackers in a minute or less without a sip of water?
Things get heavy as a two-and-a-half-ton truck makes an appearance in-studio. Michael attempts to prove to Seth and Tom something no one can believe: Four ceramic coffee mugs placed under each tire can support the entire weight of a pick-up truck. Tom's challenge of writing the number six while rotating your leg on the same side of your body clockwise seems simple in comparison but proves to baffle everyone.
What happens if you give someone a nonalcoholic drink but tell them it contains alcohol will they act drunk? Seth puts this party theory to the test to find out if drunkenness is truly in the eye of the beer-holder.

Seth is putting the nickname bird brain to the test as he hypothesizes that pigeons can actually remember human faces. And we all know that nothing feels as good as a little fun in the sun but is your swimsuit making you stupider? Michael tests the theory that wearing a bathing suit can make you dumber. And Seth does his best Flashdance interpretation for Tom's interactive experiment: Is it possible to make pudding dance and to dance on top of pudding?
The guys try gluing a man to the ceiling. Also: an attempt to separate an egg using suction; a test to see if the color red affects a bull's temper.
Could speaking in rhymes make you more believable? Seth presents this theory to the audience and the conclusion isn't just an illusion. Then, Seth suits up in the name of science to help Tom with his experiment: Can you stretch a swim cap so wide that an adult can fit inside it? And Michael's fact is just downright disturbing: Are microscopic mites living in your eyelashes?
The guys test whether bubble wrap can protect a person from a lengthy fall. Also: color effects; cow names; bouncy-ball kinetics.
Lawnmowers have a great deal of power, but can they launch debris at the same speed as a bullet being shot from a gun? Seth presents this fact to his wary co-hosts. And Michael demonstrates science firsthand with an audience volunteer for his experiment: You can use static electricity to bend a stream of water. And Tom puts Seth's face up against an anvil to prove his fact: If you hold an object suspended from a rope up to your face and let it go, when it returns, it will not hit you.
S#@%! Michael presents the first fact of the night: Swearing helps increase pain tolerance. And Seth has an experiment that is music to a gearhead's ears: Is it true that Ferraris are engineered to idle at the third and sixth harmonic? Tom's fact of the night proves just how freaky nature can be: There is a species of caterpillar that will follow each other around in circles blindly, possibly even until death! Which host has what it takes to wow the audience and win the coveted Gold Quack Award?
What's the fastest way to deliver a message: Carrier pigeon or fax machine? Seth puts this question to the test to find out if wings are better than telephonic technology. And Tom gives the audience a whiff of his hopefully Golden Quack-worthy fact: When you're in a deep sleep, smells are unlikely to wake you. Meanwhile, Michael hopes to put an age-old debate to rest once and for all: Which came first: the chicken or the egg?
Seth presents an extra-puzzling fact: The more a pool smells like chlorine, the dirtier it is. And Tom's experiment will pull at the heartstrings of even the most skeptical romantics: Is it true that your pupils expand when looking at somebody you love? Next, Michael thinks his whale of a fact will win him the sought-after Golden Quack Award: A blue whale has a heart the size of a car and its aorta is so big, a person could crawl through it.
Michael brings in three special canine guests to help present his fact: Dogs copy human yawns. He, Tom and Seth compete to see who can make their dog yawn first. Next, Tom sets out to settle the battle of the sexes once and for all: Is it true that women are better than men at remembering directions? And Seth hopes his fact will fire up the audience votes: The lighter was actually invented before the match.
Seth presents his fact that certain rhythms and melodies are more likely than others to make babies dance. Then, in the studio, he also sets out to prove there are certain dance moves that women find more attractive. To test this theory, the hosts show off their dance moves to a few gracious audience volunteers. Next, Tom shows that when you're scared, you literally get cold feet. And Michael brings on the bizarre with his fact: Coconut water can be used as a substitute for blood plasma.
Seth presents the first fact of the night: Some studies have found that redheads have a higher pain tolerance than non-redheads. Michael brings in heavy artillery for his demonstration: It is possible to climb a wall using ordinary vacuum cleaners. Meanwhile, Tom turns fresh bananas into a synthesizer that plays music. And later, Seth presents a second fact: Is it possible that after a conversation with an attractive woman, men get ... dumber?
