The other night we had friends over for dinner, and the Mom noticed that Emma's bottom tooth was pretty loose. She offered Emma five dollars if Emma would pull her tooth out right then and there. Then, to make things more interesting, she offered another five dollars to her daughter (one year older than Emma) if she would be the one to pull it out.
And of course, I got the whole thing on tape. Word of caution: this video makes me a bit squeamish. But maybe that's just because she's my daughter.
