An organ grinder and his pet monkey walk into a bar. The organ grinder plops down on a stool and the money begins running up and down the bar eating handfuls of nuts from the bowls on the bar.

The bartender complains "Hey man, get a grip on that monkey or you're both outta here!".

Before the organ grinder can get hold of the monkey it jumps off the bar onto a nearby pool table, picks up and swallows the cue ball off the table.

The bartender tells the organ grinder he owes him $20 for the cue ball, collects it then tosses them both out.

A week later the organ grinder and his monkey are back. The organ grinder plops down on a stool and the monkey again hops up on the bar and begins raiding the bowls of nuts on the bar.

To the bartenders disbelief the monkey slips each nut up his ass before popping them in his mouth and eating them.

The bartender tells the organ grinder that's the sickest shit he's ever seen and asks what the hell he's doing that for.

The organ grinder says " Ever since he passed that cue ball he checks everything for size 1st now !".
