Cougar said knock you out

The mascot of the school wherein I teach is a cougar. They asked me to create a design for a new tee-shirt to replace the clip-art they've been using for too many years. Voilà...

Now my oh-so-supportive son told me this was "cheap". I replied it was only cheap if I used the design again after this. He then made me promise not to do so.

Kids. I hate it when they keep you honest...
