A Hitchhiker
A hitchhiker is a person who stands by the road like a sad beggar, waiting for a stranger to save them from their own stupidity.
My friend hitchhiked with a guy who had a goat in the back of his van. The goat ate his sandwich.
I once hitchhiked with a man who said he was the ghost of a pizza.
A hitchhiker once got a ride from a guy who drove a flamingo.
