This is one from a while ago that I'm just getting around to posting. The funniest thing is it was worn by my student who is very demure and was shocked to find out what it meant.
...when I saw this t-shirt. Nathan tacked these phrases up on our 'weird English' board at Okaba back in the day, and I always found them hilarious. Then, Lo and behold this Friday my student Yuriko came to class wearing this exact T-shirt! I was overjoyed!
