"Mama, smell my finger."
Being the Mama of five boys I know WAY better than THAT!!! Sooo...I hold my breath, don't get to close to said finger, and pretend to smell.
"Disgusting" I say...having absolutely no clue what it is that I am claiming is disgusting. And ready to order the child to the bathroom to wash it's hands!
"I was digging between my toes."
Sigh...whew...thats far better than it could have been!
