This one has been brought to you by my little sister:
Mechanic: (putting the spare tire in my trunk and sees my old rock collection from elementary school- yes i still have it...) Are you some kind of geologist?
Me: No, I just still have it...uh.
Mechanic: My girlfriend is in geology. She is so funny. She came out of the classroom saying "geology rocks!" She said she came up with it.
Me: I'm sure I've heard that before...
Mechanic: She also said she came up with "Barack the Vote."
Me: She definitely did not come up with that.
