Too often in life we miss the obvious and need children to remind us of the things that are real. (And we may be huge nerds.)
"Dad, I've been thinking…"
"Yes son?"
"I bet Wolverine smells bad."
"Oh really?"
"Yes, he's always sweaty… and smelling good isn't one of his super powers."
"Good point."
"And the Hulk."
"Really?"
"Bruce Banner probably doesn't use enough deodorant for when he changes to the hulk."
"Anyone else?"
"Probably Thor."
"…"
"He's not from a place that even makes deodorant."
"Wow."

Great logic! It tones down the sex appeal just like a cold shower!
Awesome!
