Baka Bjanka od opće deratizacije svoje zgrade bježi kod Živkovicevih pa je Blaž prisiljen potražiti privremeni smještaj kod Špira. No, Špiro ne miruje: namješta Blažu i sebi "double date" s "dvi opake ribe". Doduše, Maja je uvjerena kako je Blaževa "riba" jos nedavno bila muškog roda pa Blažu stavlja bubu u uho kojoj će se Blaž teškom mukom pokušati oduprijeti i pritom ugroziti i Špirin "sat fizike".
Grandma Bjanka flees to the Živkovic family's place to stay after a general extermination of her building, so Blaž is forced to seek temporary accommodation with Špiro. However, Špiro does not stand still: he sets up a "double date" for Blaž and himself with "two bad girls". However, Maja is convinced that Blaž's "girl" was recently a man, so she puts a bug in Blaž's ear, which Blaž will have a hard time resisting, and in the process jeopardizes Špiro's "physics class".
