There once was a number from Nantucket...

I assigned math limericks for homework last night. Students have to compose a limerick involving "n," or "x" or some other math variable. Here's an example:

A number subtracted from ten -
I think that is ten minus n.

But I don't really know
Which way it should go

Maybe it's n minus ten.

Post a math limerick below. Let's see if you can do better than my students...  I know you can do better than me!
