They've been best friends since their high school days in East Stroudsburg, Pennsylvania. Two 27-year-old buddies who love football -- one an Ohio State fan since idolizing Eddie George as a kid, the other an Oregon fan since embracing the program's fast-paced style as a teenager.

So naturally, they watched this year's College Football Playoff semifinals together on New Year's Day -- Harry Ravese rooting on his Buckeyes against Alabama and Anthony DeBellonia cheering for his Ducks against Florida State.

That was a winning day for both -- and also the day a fateful bet was made.

"He mentioned casually that if Oregon wins, he was going to get a championship Ducks tattoo," Ravese recalled to ESPN.com, "and it got me thinking and I gave him this look and he looked back and we were both thinking the same thing."

What they were thinking was that the loser of the Ohio State-Oregon national championship game would have to get a tattoo of the other team's logo.

"Everyone that we know thought we were both crazy for agreeing to it," Ravese said.

But agree to it they did -- an especially daring bet for the tattoo-less Ravese (DeBellonia already had four prior tats).

They couldn't watch the title game together, though. There was just too much at stake. They were too passionate about their respective teams. They "probably would've come to blows," DeBellonia said with a laugh, though sounding half serious.

You know what happened next. The Buckeyes pulled away in the second half and routed the Ducks 42-20 for their sixth consensus national championship in the poll era (since 1936).

So it was time for DeBellonia's fifth tattoo -- this one clearly the most painful. "I felt bad at first," Ravese said, adding that he didn't gloat over the phone in the immediate aftermath of the victory. "But that wore off."

And DeBellonia, a man of his word, delivered on his end of the bet this afternoon.

DeBellonia did not echo that sentiment.

When asked by ESPN.com if he had any regrets, DeBellonia responded, "Yeah, the Ducks lost. Wish I hadn't gotten the bad end of the stick, but, hey, a bet is a bet."

But in case you're wondering, the loser of this bet does still plan on getting that Oregon tattoo soon -- and that one will be on his arm, not hidden on his thigh.

"I want people to see that one," DeBellonia said. "No matter what happened today, I'm still a proud Oregon Ducks fan."
