Bob goes into the public restroom and sees this guy standing
next to the urinal. The guy has no arms. As Bob's standing there,
taking care of business, he wonders to himself how the poor wretch
is going to take a leak.
Bob finishes and starts to leave when the man asks Bob to help
him out. Being a kind soul, Bob says, "Ah, OK, sure, I'll help
you."
The man asks, "Can you unzip my zipper?"
Bob says, "OK."
Then the man says, "Can you pull it out for me?"
Bob replies, "Uh, yeah, OK."
Bob pulls it out and it has all kinds of mold and red
bumps, with hair clumps, rashes, moles, scabs, scars, and reeks
something awful. Then the guy asks Bob to point it for him, and Bob
points for him. Bob then shakes it, puts it back in and zips it
up.
The guy tells Bob, "Thanks, man, I really appreciate it."
Bob says, "No problem, but what the hell's wrong with your
penis?
The guy pulls his arms out of his shirt and says, "I don't know,
but I sure am not touching it myself!"
