Don't know what show it was. it was about 6 pm EST. i'm at my daughters pediatrician's office, in the waiting room. I'm pretty sure it was Nickelodeon because Sponge Bob was on just after this show.

The teacher starts playing the bagpipes. She then appears in a kilt with huge speakers behind her - speakers and bagpipes, wow. then all the kids are wearing kilts - properly. hose but no sporrans, though.
