How about the 100 "I love you"s? After about 20, I started thinking, "You know, I think they're actually going to make me press A 100 times." Then around 40, I just started laughing at the absurdity. At 70, I realized it might have been a good idea to use my turbo controller. And at 99, I pressed Z 99 times and A another 99 times to make what just happened actually sink in. That was funny.
