The Driscolls are new neighbors, but problems arise as their phone is on a shared line with the Mitchells. Henry gets angry at Mr. Driscoll for monopolizing the line, not realizing that Dennis and his friends actually were the ones using it, and furthermore that Mr. Driscoll is a valued client of Henry's company.
