Commercials that appear to come on so much that you would very much like to die, or destroy the tv. Like those commercials that say '...if you have an erection lasting more than 4 hours...' Those drive me insane. And I don't understand the whole bathtub thing.
Timmy was just a bored little boy who enjoyed watching tv, when, all of a sudden, a repetitive commercial came on. He didn't think of it much until it had those same words as every commercial. He then proceeded to think of how he would pay money to actually get rid of commercials than actually have them advertized.
