Looks Like Somebody Has A Case of the Mondays

Damn today was whack! I was so swamped at work all day that my head was spinning for the rest of the evening. When I got home I decided to go on a bike ride with my girlfriend to relax, which promptly resulted in a popped tire a couple of miles away from my house. Walking home with a bike that has flat tires is like dragging a plow through the mud... so annoying! Hopefully tomorrow will be stress free. If not I'm going to have to join some weird cult and meditate all the time to relax, then I'll probably wind up looking like this guy.
Who is this guy anyways?
