Oh Those Teens...

Normally it's my ten year old (almost eleven, I beg your pardon) who comes out with the one-liners and the zingers. I should really do a post on them as they're hilarious.
The other day however, it was the teen's turn:-
Comes in from school, goes to kitchen, comes back upstairs (where I am but he doesn't know that). Let's out ENORMOUS burp.
Me - (Emerging from bedroom), "Oh my goodness!"
18 y/o "Ah, there you are. That was my mom locator."
Had to laugh.
