Creative Poster Ideas for Tim Lincecum or Brian Wilson? SF Giants?

Okay, so I'm gonna go to a Giants game pretty soon, && my Godfather is taking me for my 16th birthday. It's gonna' be him, my twin sisters && his daughter (my cousin). So we were thinking of making like about 2 or 3 posters. I really wanna' get his attention. Yeah, I'm pretty loud, so I can scream out his name && such but this poster is going to mean something to me. I also want it to be good enough for it to get signed. It's gonna' be for Tim Lincecum & Brian Wilson. I love Baseball, and I would really like to support my team since they're having a rough start. Please helppp! If I pick your Idea, I'll make sure to send you a picture of your poster idea! :D
