Fridge Magnet Spelling Fun

ETHAN: (bursting into laughter from the kitchen) Who did this?
ME: Who did what?
ETHAN: Who spelled this?
ME, AUNTIE SHANNON, JULIA: What??
ETHAN: Who arranged the fridge magnets to say "p-h-u-x?"
ME: I didn't do it.
AUNTIE SHANNON: I didn't do it either.
JULIA: (brightly) I did!!

Silence.

ETHAN: (cracking up from the kitchen)
JULIA: (running into the kitchen) What?  What Dad?  What's so funny?  Why?  What's wrong with those letters?  What??
ETHAN: Uh...uh...it...uh...it doesn't spell ANYTHING.  It's not a real WORD.  That's what's so funny.
AUNTIE SHANNON: (joining Julia and Ethan in the kitchen) It's just a jumble of letters.
JULIA: It spells "phux!"
AUNTIE SHANNON: Oh boy.

What unintentionally obscene word will Julia spell NEXT time she attempts to arrange fridge magnet letters?  Stay tuned!
