Dot your eyes and cross your feet

"all for you to dot your eyes and cross your feet"

It sounds like "to dot your i's... but why feet????"
Thanx

Because your fingers are already crossed. (Hint: it's a little joke.)

I believe the expression is: 'to dot your i's and cross your t's'. Meaning to make sure all is in order and completed and checked out before you proceed. Example: "This is a very important meeting Jim and you'd better make sure to dot your i's and cross your t's before you speak."
