A hard-hitting question and one well worth finding an answer for.

Thankfully, ESPN is on the case and got some information from the deadly Dutch striker regarding exactly where those old battle wounds came from.

"I was 15 years old and hanging out in bars in my home country of the Netherlands, and I was always getting into fights. And this one guy broke a bottle in my face. I had to have 20 stitches through my cheek. I've always been a fighter and always competitive. But I then started to get more disciplined and [learned how to] not be such a rebel. My brother helped me focus to get out of trouble and get me in the right direction."

Broken bottle to the face. Ouch. But he's still here.

Overeem has come a long way since then, becoming a prize fighter in lieu of joining the Army (of which he was forced to skip out on thanks to poor eyesight) and rising through the ranks to become Strikeforce heavyweight champion.

He's also now a 6'5'' 260-pound monster who goes by the moniker "Demolition Man."

One man that won't have the option of utilizing a busted bottle is Fabricio Werdum, who takes on "The Reem" this Saturday night, June 18, 2011, in Dallas, Texas.

If Overeem fights anything like he has been of the past few years, though, "Vai Cavalo" just might need one.
