Womb

On a bus one day were two boys and a middle aged woman reading her book.

The two small boys were having a deep heated discussion on the subject of
spelling.

"It would be spelt W-W-W-W-O-O-O-O-M-M-M-M-B-B-B-B"

"No its not. It's spelt W-W-W-O-O-O-O-O-O-O-O-M-M-M-M-M-M-M-B-B-B"

The lady leaned over and said, "Excuse me boys, but I think you'll find the
word is spelled W-O-M-B".

The first boy looks at the other, and then back at the lady, and replies,
"Ya know lady, I bet you've never even seen a hippopotamus, let alone ever
heard one fart underwater

W-W-W-O-O-O-O-O-O-O-O-M-M-M-M-M-M-M-B-B-B
