The "I'm Tired" Signal.

When I'm exhausted, my body sends signals to my brain indicating so. Apparently that's not the case for dogs. Monika and I are dog-sitting for friends this weekend, and their dog is absolutely relentless. Send him outside to run a marathon in the backyard - it does nothing. He comes right back in and runs circles around you, jumping and biting incessantly.

I just read an interview with Jay-Z that gives me an idea. Someone get this dog some weed!
