Keanu Reeves is an actor, and a succesful one at that, but he has no qualms about going up to someone and asking them for an autograph.

Reeves recently appeared on CBS' "The Late Show With Stephen Colbert" to participate in a round of "The Colbert Questionert" where he was asked if he had ever walked up to anyone for their John Hancock and he said he had, but only twice. Once was for the autograph of The Velvet Underground's Lou Reed, and another time, to legendary comedian George Carlin.

While revealing that he did approach Reed for an autograph, he mentioned it was not for him, but for a friend. "But it wasn't for me, it was for a friend," Reeves recalled, adding that Reed "was cool about it."

"It was like a little piece of paper and blue ink... it just said 'Lou Reed,'" Reeves told Colbert. 

"It would have been really disappointing if it didn't say 'Lou Reed,' " joked Colbert, to which the "Matrix" star replied, "I know, but it could have said, 'All my best' or like, you know what I mean?"

The two went on to joke about all the possible messages Reed could have jotted down on that "little" piece of paper, per Entertainment Weekly.

Then, just as Colbert was about to move onto another question, Reeves shared that Reed wasn't the only one he asked for an autograph from, adding that this one was most certainly for himself—from George Carlin, whom Reeves has worked with in "Bill &Ted's Excellent Adventure", as well as "Bill & Ted's Bogus Journey."

"I am so jealous," Colbert said in awe. "I'm such a fan." Carlin died in 2008 of heart failure in Los Angeles, per Reuters. He was 71.

"He wrote, "Dear Keanu, f**k you," Reeves recalled with a laugh. "I always thought he just wrote that for me. And then I met someone else that he wrote that same thing to them. Anyway, beautiful."
