Behaving I-gnome-iniously

(I’m in an English class, which is a complete joke. The teacher has a good sense of humor and understands how bored the class is.)

Teacher: “It’s like having a thousand little gnomes gnawing at your feet! No one wants that.”

Me: *no idea what he’s going on about and slightly confused* “Why are we talking about your fetish?”

Class: *bursts out laughing*

Me: “What?”
