Harold tries to prevent the plot from advancing by doing nothing but sitting and watching TV... so the plot bursts through his wall and eats his television!
Even more hilarious, when he turns on the television, it runs a number of nature documentaries that show animals dying in horrific ways. Harold desperately wants to change the channel...but can't because he promised himself that he wouldn't do anything.
Also, Doctor Hilbert's quiz that he gives to Harold to determine what kind of story he's in.
Dr. Hilbert: Aren't you relieved to know you're not a golem?
Karen: (narrating) "Why was Harold talking to this man?... This man was an idiot." And Harold gives a sort of half-nod as if he agrees with his narrator.
"He was elated and surprised by his somewhat flirtatious encounter with Miss Pascal. So elated that he exited the Transit Authority Bus a good twenty-seven blocks early and would now have to walk." Cue poor Harold turning back to try and board the bus again, to no avail.
