Bathero

Bathe.
Hero.
Bathero.

Once as a kid, I went to bathe and forgot to take my shirt off first.

And it was a Superman shirt, which basically amplified how NOT super I was being.

Though in fairness, Superman's powers DID develop one at a time...
Flying came last, preceded by heat and X-ray vision, which appeared in turn after super speed, strength, and intelligence necessary to get undressed fully before bathing.

Shampoo.
Powers.
