If only John Force, the colorful 17-time Funny Car champion (one in the ADRA), had a dollar for every autograph he's signed in his illustrious career. 

Those dollars could likely field a fifth John Force Racing nitro entry. 

Force has signed it all, including a pig. Yes, a pig.

"A guy came up to me one time with a pig," Force recalled while appearing on the CompetitionPlus POWER HOUR on Tuesday evening. "I said, "Well, you carried this all the way to the racetrack to sign it? And this little pink pig, so I signed it."

Force has even declined to sign one item, which we will leave up to the imagination, and it drew the ire of a biker.

"Yeah, I've had women, beautiful women, and their boyfriends right there with them," Force revealed. "I had a big old biker guy who was going to choke me because I said, 'I won't sign her. She's beautiful. Why would you want to sign something that beautiful, that woman?" 

"I thought the guy was going to beat me up."

Of course, there was the one item that Force was going to sign but was told not to. Last weekend in Barona, Force happened across a Johnny Cash impersonator.

"I actually, I was going to try and hinted around signing his guitar, and he goes, 'Nobody signs my guitar," Force said. "I think it was a real Johnny Cash guitar."

While Force has truly been everywhere, the one place, he hadn't been revealed itself. Force was asked to sign a race fan's leg, and he went to bend down to sign the leg and got the surprise of his autographing career. 

"I got people that have John Force's signature on their legs," Force said, playing off the moment. "They got race cars; they got pictures, my daughter's faces on their legs and stuff. And he said, 'Could you sign my leg?" 

"I said, "Oh yeah," big old crowd, a bunch of people standing there he goes, "Yeah."

"The guy stood on one leg, and he pulled his leg off. And I don't know, he lost his leg, maybe it was in the war, and he handed it to me, and he's sitting there hopping. And so I took it, had his shoe on it and everything, and I started signing it, and then a fan starts yelling at me. I turned to the fan, I got talking, and I forgot this guy's behind me hopping. 

"I turned around, I said, 'Oh, I'm sorry. Here." 

"I gave his leg back. And that was probably the most stunning thing, but he can hop on one leg better than I can hop on two."
