An Alien?

There was some discussion this weekend as to wether or not Yogi is an Alien. I mean how else do you explain his "ability" to aquire any seat in the house without someone putting up a fight? He can de-throne Sherman with nothing but a stare, and Sherman says: "Okay I give up,you can have my spot. Sometimes when he looks at your food while your eating this alien ooze comes out of his mouth and it causes everyone to give him thier plate too! Just to error on the side of caution, we have given him a tinfoil hat to keep him from contacting his kin. Good grief what would we do if he called in for back-up!
