Meriwether Koozie - Bigfoot
Bigfoot Hide-n-Seek World Champion.
It's no coincidence that Bigfoot has never been discovered or even caught on film (other than grainy footage from far away...) This species has some serious Hide-N-Seek skills.
While not an officially recognized Olympic sport, there is little doubt Bigfoot would be World Champion if it were. Even the blood doping Russians couldn't match his skills at hiding in plain sight.
OK, Sasquatch, you win. Come out, come out wherever you are!
