I haven't seen it (and wouldn't have the volume up if I did), but it has two correct pronunciations:
gradu-8: verb (I didn't graduate from HS.)
gradu-it: noun, adjective (I'm a HS graduate; I went to college and got a graduate degree.)
I had a cat who would do this until probably his mid-teens. could not leave the stuff out (and keeping the bathroom closed wasn't a good option, either).
