Nathan Fillion visited the set of Community today ... but why? Is the Castle star set to make a guest appearance on the hilarious NBC comedy?

Unfortunately, no. He tweeted (@nathanfillion), "Dropped by #Community to say hi to @joelmchale. Congrats on those ratings! You guys are kicking ass! I love Community!"

We do, too! And we think Nathan's witty, droll sense of humor would fit right in with the Greendale Community College crew. TV gods, make this happen, please? We can totally imagine Nathan as a smirking women's studies professor who riles up Britta and Annie!

Community star Joel McHale (@joelmchale) also had a little Twitter fun with Nathan's visit, writing, "He's consulting on our Firefly/Serenity parody. #this-is-a-lie."

Uh, TV gods? We have a second favor to ask ...
