He arrived at the Maui Pad as a pledge with Shay in June of 2008! Gone by September, but visited once in November. Then he didn't move in as an active until the Arizona Pad, April of 2009, staying until December. His last big stay I believe was from April of 2011 until February of 2012, though I have his last appearance as being March 24th, 2013. Could have been just a brief visit. That was a few weeks after Leo had been abruptly fired.
He was scheduled for a duo with Shay July 5th, 2008 that I imagine he got cold feet for, since it was canceled. It was replaced by the Diego/Shay duo on July 12th. Since then he avoided duos until one with Jayden toward the end of his career, only featuring handjobs. Mostly a side-by-side. (I found it here:

But I tend to think of him as a sort of Fratpad mascot for all of 2009. The guys really got along with him and his goofiness and they would mimic a lot of his noises and vernacular. They all called him "Kerm" or "Kermie" and I've been so desperate to learn why. I mean, I have to imagine it has to do with Kermit the Frog lol. I think it happened very early on. If anyone knows the story, I'd be so grateful haha. I'm back and forth wondering if they thought he looks like Kermit or sounds like Kermit. I have a suspicion it came from Leo, since he's the one who really made things stick at the Pad.
But yes, when I was younger and first discovering the Fratpad, I always thought that "Kermie" and "Calvin" were two different Fratmen that looked shockingly alike. Fun fact. About...me.
