How is being at the singles bar different from being at the circus?

At the circus the clowns don't talk...

Six guys were playing poker when Smith loses $500 on a single 
hand, clutches his chest and drops dead at the table. Showing 
respect for their fallen comrade, the other five complete their
playing time standing up.

Roberts looks around and asks, "Now, who is going to tell the 
wife?" They draw straws. Rippington, who is always a loser,
picks the short one. They tell him to be discreet, be gentle,
don't make a bad situation any worse than it is.

"Gentlemen! Discreet? I'm the most discreet man you will ever 
meet. Discretion is my middle name, leave it to me." 

Rippington walks over to the Smith house, knocks on the door, 
the wife answers, asks what he wants.

Rippington says, "Your husband just lost $500 playing cards."

She hollers, "TELL HIM TO DROP DEAD!"

Rippington says, "I'll tell him."

Q: What do you call a black smurf?

Seven friends once pulled this at my college cafeteria.
One put a hot water bottle filled with pea soup down his chest;
he sat at the head of a table, with the other six friends
sitting along the sides.
When the cafeteria was pretty full of people,
he made a loud noise (to attract attention),
stood up, bent over and squeezed his chest.
This caused a huge gush of green liquid to spew all over the table;
the other six immediately began to eat this green liquid.
I think a lot of food went uneaten that night.
