If Hobbs was a horse, all you would have to do is to load him on a horse trailer and HE WOULD POOP!
I've never heard of the match stick thing, but I am going to tuck that idea away for future reference. It makes sense that he would use his pooper muscles to expell the offending foreign object sticking out his pooper place.
Hobbs, I know this isn't funny, I'm sending you hugs
