Flannel Shirt Puns

Went on a date with a girl, and she was wearing a flannel shirt. She mentioned how her friends who are into fashion would kill her if they knew that she went on a first date in a flannel shirt.

I saw opportunity. I reached over, felt the arm and said, "this isn't flannel, is it felt?" She responds "No, I just said its Flannel" but I cut her off and said "IT IS NOW"

She didn't leave immediately, and we are going out again. Figured would let her know what she was getting into right away.

My friend is designing a t-shirt for Folk Fest and needs a witty, all-ages-appropriate pun to go on it, but neither her, nor I or my fiancee can come up with one. The image on the front is of a beardy man playing the tuba, with a bird (Cardinal, I think?) coming out of it that's playing the drums. Out of the bass drum is crawling a cracked-out-looking dude wearing flannel, who's playing the guitar-looking instrument, with arms coming out of that playing the triangle. A great pun for the shirt with the word "Folk" in it would be much appreciated, and I know you guys are good at making puns, so fire away! Reddit, lend me your puns!
