I only do this with close friends/classmates but I like to take new grammar/vocabulary and try to incorporate トイレ into a sentence using it as a bit. It’s not very funny and every one is sick of it 2 years in to studying together but it makes me laugh.
Also caveat to only doing it with close friends but my sensei overheard me in 101 and started doing it too.
Anyway, do you have any bits you like doing in Japanese?
