Show-Related Doggerel

Rehearsal for The Beauty and the Beast continues at K's school. As a member of the chorus, she ends up playing a number of small parts, now including a plate in one of the numbers. Of course, trying to get these things coordinated is a problem, which caused me to compose this short fragment, which I have not yet introduced to K:

I'm a plate! I'm a plate!
And I've made my entrance late!
Now the blocking is all busted,
The director is irate!

And that's probably all I need for that...
