When I showed this shirt to Calfgrit10, he immediately burst into laughter. Loud laughter. So loud that his little brother came running from across the house to see what was happening.
When Calfgrit6 arrived, and looked, big brother pointed to the t-shirt and said, “Spell that.”
After he spelled it out loud, he smiled in slightly embarrassed humor, and Calfgrit10 again burst into raucous laughter. I took all this as proof that this design is a hit with the 10 year old and under crowd.
And then CG6 spent the rest of the evening spelling icup out loud, and CG10 spent the rest of the evening overreacting to the joke.
