"Yo" Curse

There's one way to make "Yo-leven":
Six plus five adds up to eleven.
It's just as hard to make verse
As to beat the "Yo" curse
Without using "seven" or "heaven".

I don't think I can think of five different ways to make "11" limericks this week. I could come up "snake eyes" tomorrow.

So I'm posting this excuse today. :)

Note: "Yo" is short for "Yo-leven" which is shooters' talk for "Eleven".
