this is at least five years coming...
i've been trying to decide which song i'd walk up to the plate to if i were a major leaguer, and it finally hit me on saturday night...50cent's In Da Club.
the lyrics -
It's your birthday
We gon' party like it's your birthday
(don't read the rest of the lyrics, 'cause they're nasty)
the ESPN article from 2004 is here.
