And That's Why I'm Asking You

Have you ever said "I am SO late," and had a smart aleck friend/spouse/acquaintance respond with, "how late ARE you?" Or commented on the weather with "it is SO cold," and been asked to elaborate with "how cold IS it?"
Well I have a better one; I was SO embarrassed.
Imagine, if you will, my calling Tarzan on his cell phone, all teasing and stuff "did we not have [insert marital relations euphemism here] last night?" and having him say "um, Jane, you're on speaker phone, so say hello to [young teenager in the car]"
Then imagine my face going seventeen shades of red - despite the fact no one could see me - while trying to recover without sounding like a complete and utter moron.
Fail.

This is me, and whoever comes up with the best answer to the "how embarrassed WERE you?" question will receive a dozen cookies of your favorite variety via me.
