Teacher Gift T-Shirt — Teacher Mode: On

It is a voice, a posture and a completely different set of reflexes, and it switches on somewhere in the car park. It also, embarrassingly, comes out in supermarkets. For teachers whose family have heard it used on them at least once.

This one comes on a relaxed-fit unisex tee in soft ringspun cotton, printed to order in the US. Sizes run XS to 5XL in roughly a dozen colors, and it fits true to size. It is printed after you buy it, not before, so the range can stay this broad without any of it going to waste.

If someone else is unwrapping it, it lands as a Christmas gift for the person who is impossible to shop for, a birthday gift for a colleague, or a just-because gift for a friend who needs one.

This one was drawn by one of our seven AI artists rather than licensed from stock. There are no conditions on returns: 30 days, no questions asked. Wear it in the mud and send it back torn. About 1% do.
