In the Name of the Worst Within You… Again
The comedic element in this commercial is, obviously, the fact that the phrase “pull one off” is an (unintentional) allusion to masturbation. The commercial is funny because even though technically it’s completely legitimate to use that phrase in regards to how the advertised product is consumed, provided that there are adequate alternatives, it’s one that shouldn’t be used because of it’s similarity to a vulgar slang term. That begs the question, however: why, exactly, is that particular phenomenon considered funny. The answer can be found here, in an analysis of another commercial which has a similar object of humor.
