Went into a Bar. Ordered a martini.
There was a little monkey on the bar, begging for treats. I flipped him the olive. He caught it on the fly, sniffed it twice, stuck it up his ass, pulled it out and swallowed it whole. "What's up with the monkey" I asked? The Bartender says
"Well, there was this guy fed him a billiard ball". "Now he measures everything to make sure it will come out the other end".
