A guy walks into a bar and orders a beer. “Listen,” he says to the   bartender. “If i show you the most amazing thing you’ve ever seen, is   my beer on the house?” “We’ll See,” says the bartender. So the guy   pulls out a hamster and a tiny piano out of a bag, puts them on the   bar,   and the hamster begins to play. “Impressive,” says the bartender, “but   i’ll need to see more.” “Hold on,” says the man. He then pulls out a   bullfrog, and it sings “Old Man River.” A patron jups up from mhis   table and shouts “Thats’s Absolutely incredible! I’ll give you $100   right now for the frog.” “Sold,” says the guy. The patron takes the   bullfrog and leaves. “It’s none of my business,” says the bartender,   “but you just gave away a fortune.” “Not really,” says the guy. “The   hamster is also a ventriloquist.”
