This is how I've been torturing my daughter. I'll get out of the shower and put pants on (one leg at a time like you guys) then realize I'm out of deodorant. So I'll stand in her doorway and sloooooowly reach my hand in toward her deodorant.
Daughter: Oh no Dad. Please?
Me: (acting surprises) Oh what? Sorry. I just need to borrow some of your precious deodorant.
*Slowly applies deodorant and makes a face as if it's super refreshing*
Me: Awww yeah that's doing it....Yup.. Wait. Why are you making that face? Like you just smelled eggs or saw something gross. Wait? Do you think I'm gross??
Daughter: No...uh...nothing. That's OK.
Me: OK. Let me just finish up here and I'll be on my way. (does one last swipe) Annnnnd DONE!
Sometimes I'll leave the room and come back....
Me: Sorry. I think I missed a spot...
