Bad puns from me to you

Gregular Expressions started with a single terrible pun: Gregnant. It was too bad not to share -- so it became a whole shop of deliberately awful Greg wordplay, from terminal jokes ($ grep -i "greg" *) to office parody (Assistant to the Gregional Manager).

Every design is made for programmers, developers, and anyone named Greg: monospace type, glowing green text, zero apologies. If you've ever snort-laughed at a regex joke, you're home.

All products are printed to order by my production partner Printify and shipped straight to your door. Thanks for stopping by -- and remember: keep calm and Greg on.
