At the start of repairs on Benny's house, the gas is turned off by the pretty assistant. However, later in the show, the audience learns the gas was already off due a leak at the kitchen stove, so it didn't need to be turned off.
Benny has to stay at Tim's because he "blew up his house." Tim climbs down the roof, and sees Benny doing exercises through the window. When Wilson asks what's wrong, Tim explains that he saw Benny doing "Pelvic thrusts." However, none of the motions Benny does are pelvic thrusts.
At the very end of the show, after Tim deposits the large branch into the sink, he turns the tap to let the water run. However, no water comes from the tap.
