Michael Guill — Founder & Designer

I started Misbehaving Merch in 2020 because I’d seen one too many “funny” tee ideas that could’ve been so much better, and because I was tired of the shirts marketed to women being either boring or, worse, a little bit misogynistic in a way everyone just pretends not to notice. I wanted to make stuff that was actually funny, actually filthy when it wanted to be, and built around female empowerment instead of at its expense.

I design most of what’s in the shop, write all of it, and personally approve every sample before it goes live. If a shirt says something filthy, I wrote it. If the pun is bad, that was a choice.

We’re not just tees: hats, journals, phone cases, and more are in the mix too. Most of our shirts are printed on Bella+Canvas Airlume combed and ring-spun cotton, made by a Platinum WRAP-certified, Fair Labor Association manufacturer. That part isn’t a joke… it’s the one thing I won’t cut corners on, wherever it’s used.

Outside the shop, I’ve spent twenty-five years building things on the web and ten leading digital experience teams, which is mostly why this site loads properly. I also run Browncoat Digital, a small independent web practice.

Based near Omaha, Nebraska. Reach out through the contact form on this page: I read everything, including the complaints.

Got a Problem? A Genius Idea? A Hot Take?

Whatever’s on your mind, we’re listening — mostly. Shirt showed up wrong? Idea for a design so unhinged it might actually work? Just want to tell us we’re doing great? This box is for all of it.

Drop your order number if it’s refund-related (we’re good, not psychic), pick a topic below, and let it rip. We read every single one, and we usually write back within 1–2 business days.

No corporate hold music. No “your call is important to us” while you question your life choices. Just us, actually paying attention.
