WOW...this guy must have been really desperate!

Last week, 64-year-old Kenneth Guillespie of Darwen, Lancashire, England was walking down the street drunk, when he spotted a snowman.  And he carved himself a little hole in that snowman, so he could have sex with it.

By the time he was done, the five-foot snowman was basically destroyed . . . and Kenneth was screaming in agony.  Because he'd gotten FROSTBITE ON HIS JUNK.

According to the hospital where he was treated, there's a chance that Kenneth's junk may have to be amputated, but so far, quote, "[he] is still in one piece."

He's not facing any criminal charges.
