Mushroom Suicide

Alright listen up, you wouldn't get it, but I, Explain Bear, am here to help your puny mind! This joke is all about wordplay. You see, a mushroom is a small fungus, but it's also slang for a small room. So, the mushroom killed himself "in the mushroom," get it? I can't believe I have to lower myself to your level. You should be reading books instead of posting silly jokes.
