Randomtistosis Is What It's Called.

I'm afraid I have Randomtistosis,
And it is quite contagious too.
It does not matter how many doses,
Are taken, I'll still embarrass you.

"Bloody Murder!" I'll scream. "Yay ice cream!" I'll Shout,
I'll hug a complete stranger, and merrily skip down the hall,
No matter what, I always seem to blurt out,
A sentence with no relevance at all!

I stop what I'm doing in class,
And break out a move or two.
I'll point out that a donkey is an ass,
And that I learned that from Shrek 2!

I laugh at my own jokes,
I can interrupt any awkward silence,
I chase after all the blokes,
Just to tell them Santa and I are in secret alliance.

So my friend, here is a heads up,
Randomtistosis is what it is called.
My mates are trying to get me to shut up,
and away I'm being hauled...
