When former Firefly co-stars Nathan Fillion and Adam Baldwin reunited on the set of Castle this past season, they immediately returned to their old antics.

Not surprisingly, the pair began tweeting back and forth, attempting to one-up the other with a series of hilarious posts. But little did Nathan know, one of his tweets would take on a life of its own…

"Needs 2b a t-shirt that says 'I wish this was Nathan Fillion' with a -->. And have people wear it next to @adamsbaldwin," Nathan wrote, tongue-in-cheek.

A few days later, multiple T-shirt companies had produced the garment, selling it online in a variety of different colors, styles, and sizes. Nevermore Shirts is currently selling the shirt on Redbubble.com for $24, and Spreashirt.com has it for $22.

Some Fillion fans have already tweeted pictures of themselves wearing the snarky tee, and we have a feeling we'll see even more at this year's Comic-Con!
