how you know if you're disturbed:

You start singing either of these:

One potato
Two potato
Three potato
Four
Five potato
Six potato
Seven potato more
Eight potato
Nine potato
And now there’s ten
We’re smothered by potatoes
And we have to start again

 

Water water everywhere
Oh look I drowned

Oh, and don't forget this one, either:

Hey, diddle diddle,
The cat's in the fiddle
And the house jumped over the moon.
The three blind mice
Were sliced and diced,
And the rabbit got put in bunny stew.
