I'm sure other parents do this. You see someone, maybe a fictional character on television, an altruistic public figure, one of the last upstanding professional atheletes, or just a really nice kid who works at the mall, and you think, "Man, I hope my kid grows up to be like that."
While obviously we don't want our kid to be exactly like anyone else, there are definitely qualities we admire in other people's offspring, qualities we aspire to endow in our children.
Now, I am a huge Gleek (fan of the show "Glee", for the uninformed), and there are tons of things I love about it: the songs, the storylines, the positive messages. But I think a lot of the appeal in it, for me, is that it's filled with so many mom-crushworthy guys.
