I recently posted about people who get tattoos that either say nothing, or something terrible, as featured on the website Hanzi Smatter. There are websites (such as engrish.com) that highlight bad translations.
There really should be a website featuring people wearing teeshirts that they don’t understand.
Gotta Catch Them All Ages, Part 2 (From Not Always Right)
(A customer in her sixties comes in to buy a ticket. She’s wearing a sweatshirt that has the Pokémon Magikarp saying, ‘I swear to God, when I evolve, I’m going to kill you all.’)
Me: “Do you like Pokémon?”
Customer: *offended* “Pokémon?! No! Why?”
Me: “Well, that’s a Pokémon on your sweatshirt. It’s an awful one, but it evolves into one that’s totally awesome!”
Customer: “This is a Pokémon? I thought this was a statement about atheism!”
