I'm so glad you enjoy them. I'm a big fan of cleverness, silliness, and nerdiness. Not to mention they are adorable together. They are officially Kate Micucci and Riki Lindhome, but go musically as the duo "Garfunkel and Oates".
If you're a fan of Chris Hardwick (Nerdist Industries) and/or stoner comedian Doug Benson you've probably already heard of them. In fact, G&O trivia - Doug Benson actually introduced the two to each other (thinking they would hit it off). And the rest is history. The first song I heard of theirs was the Handjob Song and the second was The Go Kart Song. And I was hooked.
I listen to the Doug Loves Movies podcast and he has them on often. For the record, I don't inhale - I only listen because I'm a big movie buff.
They are like Key and Peele for me, even their mediocre stuff is better than just about everything else out there. Their raps are loaded with nerd and pop culture references (check out the Handjob Song and This Party took a turn for the douche - brilliant).

One of the funniest verses ever written:
"This might be strange to tell you
and I swear I'm not a whore
I have 206 bones in my body
and I'd really like one more."
