Depends who they're playing Whits. If its the San Francisco Giants, you can holler abuse towards Barry Bonds (he of steriods fame and about 5 off all the all-time home run record).
If not, just get pissed and throw peanut shells over the people in front. Don't go high-fiving babies though - not popular

High fiving babies, seems like there should be more of a story here? Please do tell.
I'm going to start drinking about 3ish, should be a good crack....though i don't really know the rules and whats going on....i'm thinking about singing "poor mans rounders, its just a poor mans rounders" but not sure many will follow
I went to watch the Cincinnati Reds play San Francisco Giants for my birthday a couple of weeks back. We had seats out by the LF, who just so happened to be Barry Bonds. Having had one or two sherberts too many, I started chanting 'Your shit and you know you are' every time the druggie was close enough, and high-fived a one year old when the Reds scored a 3 Run Homer. Not my greatest moment in life to be honest, but I enjoyed it.
I don't think the locals quite got it though :?
