This is actually pretty interesting, not a joke about rickthelion.
I say that any animal that eats their meals butt-first is kind of ace!
On the joke side, I can't remember if rickthelion met rickthevulture in Africa or America, but I always pictured rick as a turkey vulture! Perhaps rick will provide more information!
When I moved from Chicago to San Antonio, one of the first things I saw was a flock of vultures devouring the carcass of a deer on the side of the highway. I knew I was in a different state.
