The one about the nun's gas...

Sister Ann, aren't you putting on a little weight?" inquired Father Dan during his visit to the convent, suspiciously eyeing her bulging stomach.

"Why, no Father," answered the nun demurely, "It's just a little gas."

A few months later Father Dan put the same question to the nun noticing her habit barely fit across her belly.

"Oh, just a bit of gas," said sister Ann, blushing a bit.

On his next visit Father Dan was walking down the corridor when he passed Sister Ann wheeling a baby carriage.

Looking in, the priest observed, "Cute little fart!"

The one about the Chinese man...

A Chinese man arranges for a hooker to come to his room for the evening. Once in the room they undress, climb into bed, and go at it.

When finished, the Chinese man jumps up, runs over to the window, takes a deep breath, dives under the bed, climbs out the other side, jumps back into bed with the hooker and commences to repeat the performance.

The hooker is impressed with the gusto of the second encounter. When finished, the Chinese man jumps up, runs over to the window, takes a deep breath, dives under the bed, climbs out the other side, jumps back into bed with the hooker and starts again.

The hooker is amazed as this sequence is repeated four times. During the fifth encore, she decides to try it herself.

So when they are done she jumps up, goes to the window and takes a deep breath of fresh air, dives under the bed...and finds four Chinese men.

The one about the horsey ride...

Little Johnny is passing his parents' bedroom in the middle of the night, in search of a glass of water. Hearing a lot of moaning and thumping, he peeks in and catches his folks in The Act. Before dad can even react, Little Johnny exclaims "Oh, boy! Horsy ride! Daddy, can I ride on your back?"

Daddy, relieved that Johnny's not asking more uncomfortable questions, and seeing the opportunity not to break his stride, agrees. Johnny hops on and daddy starts going to town. Pretty soon mommy starts moaning and gasping.

Johnny cries out "Hang on tight, Daddy! This is the part where me and the milkman usually get bucked off!"
