Water in the pipes

Overheard at dinner tonight:

MH (takes a sip of water and starts coughing and sputtering)
Mommy: Sweetie, are you OK? Did it just go down the wrong pipe?
MH: yeah mommy, it went right down the wrong drain.

MH then proceeds to continue talking about how she's fine, her water just went down the wrong drain. What a crackup.

Gotta love how literal they can be and how quick we are to forget it!
