If at a meeting you hear the phrase 'Movin' Right Along' and you're prompted to sing 'Movin' Right Along, Footloose and Fancy Free.'
I totally did that in my math class last year.
Constantly. XD
Ooh! I just thought of some good ones!
~ ... you incorporate a HUUUUUUUUUUUUUUUUUUUUUUUUUUUGE Muppet reference into a story that normally would have absolutely nothing to do with Muppets. (I'm gonna replicate the Escher room scene/"Within You" number in my Super Paper mario story as best as possible! XD)
~ ... whenever your math teacher says "Moving right along", you burst into song, resulting in an evilish stare that only math teachers can give.
~ ... you give your Rescue Team on Pokemon Mystery Dungeon a Muppet-related name. Examples include "MuppetNuts"(mine), "PigsnSpace", "Fire Gang"(technically impossible, since you and your partner can't have the same type, so you can't have an all-Fire Rescue Team... I'm rambling again, aren't I?), etc.
~ ... when someone says "That's not fair!", you reply with "You say that so often, I wonder what your basis for comparison is?" (Mom needs to do that with me, maybe I'll stop complaining about unfairness then...)
~ ... if someone says "Muppets are stupid", you karate chop them a la Piggy. (True story. XD)
