What should I art?

I haven't drawn anything non work related in a while, so how about you guys give me an idea of what I should draw (keep it PG please). Just make a suggestion of what to draw on this post and I'll pick a couple that sound fun and draw them, and if I choose yours I'll mail it to you for free.

How about that? Free art!

I'll choose on Wednesday the 20th so anything posted from now till then is fair game.

UPDATE!

Thanks for all the comments guys! Great response for this, I'll probably do it again if I continue to have this kind of response.
I was just going to do two pieces but there are so many fantastic ideas I'm probably going to do a handful more. 

Check back later and see if I chose yours.
