Nothing says "I'm a fun, energised improv nerd" like a Boom-Sha-Boom tee. A true conversation starter (and ender). Wait until someone ask what it means - enthusiastically teach them the song and all the moves... then gleefully watch their eyes fill with regret as they fade away into obscurity.

100% organic ring-spun cotton is where it’s at. This t-shirt is soft, thick and super comfortable!

This product is made especially for you as soon as you place an order, which is why it takes us a bit longer to deliver it to you. Making products on demand instead of in bulk helps reduce overproduction, so thank you for making thoughtful purchasing decisions!
