Kids Know the Darnedest Things

This was from an incoming sixth-grader this morning...

ME (after a note struggled to come out): That one had a little trouble.
KID: Yeah, I need to ret my weed. (Laughs) Did you hear that? I said "ret my weed." I spoonerized!
ME: Wait...you know what a spoonerism is?
KID: Of course! Because they're so much fun!
