Johnny Knoxville's ball-busting stunt

Jackass star's backflip goes slightly, err, wrong

Every man's worst nightmare come true

OUCH. Ouch. Ouch! Here’s one to make you wince in only away a man can understand.

Jackass star Johnny Knoxville has been injured while filming a tribute to Evel Knievel for MTV. The special, under the over-seeing eye of freestyle God Travis Pastrana, is due to be aired around February 23 – and will most likely include the accident that left Knoxville bleeding heavily from his nads after trying a backflip on a motocross bike.

Here’s what Knoxville himself said: “Just got back from Oklahoma where I was shooting ‘Mat Hoffman’s tribute to Evel Knievel.’ Had a ball, too, even though I almost lost my own balls in the process. Don’t want to give too much away because the tribute airs Feb 23rd on MTV, but let’s just say before letting Travis Pastrana teach me how to do a backflip on a motorcycle I should have had him teach me to ride one first. Heh-heh… Bad for me, good for our viewing audience at home. Have to go now. Have to empty the p*** bag on my leg that I have to wear for the next two weeks until my torn urethra heals. Ouch, and see you on the 23rd. By the way, lots of great stuff in the Evel Knievel tribute besides my trip to the hospital—lots!”

What a star.
