From about 2002 or so.

I drew an animal rock band. Couldn't figure out what to do with them, but it was fun while it lasted.

This is Roger and Casey, the 2 guitarists.

I gave the original to Matt Crocco, co-creator of the Sifl&Olly show, who I was acquaintances with at the time, for his birthday.

He emailed me back and said "Dude! How much do you rock?" ^_^
