Comedian Jason Segel was left speechless after a fan propositioned him with a self-penned track in his honor.

Chelsea Gill plays guitar along to her song, in which she asks The Muppets and Forgetting Sarah Marshall star to "just have a drink with me before this year ends".

Other lyrics from the tune, which has been posted online, include, "Now I know you're super busy, what with Sarah Marshall and Miss Piggy/ But I swear I'm worth your time, just wait and see. Now I know what you're thinking, another crazy girl with heightened feelings/ But I swear I'm sane, tested, and disease-free.

"Oh Jason Segel, it's important that you know I'm legal/ so any crazy s**t you wanna do, just know I can do it too. Have a drink with me, oh Mr Segel can't you see/ I'm trying so hard to impress, you're so f**king hot but I digress."

Segel spotted the video and he's overwhelmed by Gill's efforts to meet him.

In a series of posts on his Twitter.com page, he writes, "My favorite thing, maybe ever. I am in awe. Response on the way... I'm gonna need a couple days on this one."
