It depends on how memorable the quote was. Something as generic and soppy as "Show me the money" is something that was blasted at pop culture.

Being a Simpsons nut I used to have a challenge with a friend when doing my Undergrad were some point in the day I would use a Simpson's quote in a conversation with him within ear shot and he had to acknowledge it and therefore continue the quote...... yes I am a geek
