Segel showed up on stage at a Swell Season show in Los Angeles on Wednesday and played a song he'd written to try to get a date. It's fantastic, and features a chorus where he sings aloud what's ostensibly his phone number while Marketa Irglova holds it aloft for easy dialing.

Sample verse:

Well, I know you're charmed by my lovely on-screen persona
Sweet and humble, that's certainly my career
But it would be a shame for you to miss this one-time offer
To make love to Jason Segel this year.

If you're curious whether or not he makes reference to showing off his penis in Forgetting Sarah Marshall... well, you really shouldn't be.
