Evidently Han Solo was in every episode of Firefly. Check this out:

That’s an awesome little joke! I can’t wait for the definitive list to be compiled!
Very cool.
According to the comments, he wasn’t in every episode; Nathan Fillion always tried to sneak him in, but didn’t always succeed.
I like it.
I wonder if he’s ever made an appearance in “Castle”.
That’s awesome, and perfectly Fillion.
He knows you love it.
Sweet.
I find it difficult to see it in the fourth picture. But that’s mostly because that one has Kaylee in a hammock, and it’s therefore difficult to maintain concentration on anything else in the picture.
