Why does Superman wear his underwear outside of his pants?

for more definition.

you're all incorrect. Years in the past, Superman made a gamble that his roundhouse kick become better then Chuck Norris's roundhouse kick. The situations of the wager suggested that whoever had the weaker kick had to placed on their underpants on the exterior of his pants.

Because when he is needed, he has to dress really fast and in dark phone booths.

Wonder where he changes now that all of the phone booths are gone?

i suppose it's because he bought a size too big, so rather than going to the store to exchange them or buy a new pair, he just wore them outside of his tights so they would fit. he figured that as super-elderly-man, he would grow into them. then it became a staple.

He gets dressed in a hurry or maybe he is dyslexic?

Style baby, pure style!

he likes the way the tights feel againest his parts

have you ever tried getting dressed in a phone box?

Well Duh! This is how he keeps his underwear clean. You see, when he gets scared, he poops himself just a little, and it all kinda sloshes down into his boots.

He's proud of his tighty reddies

Because that's what his mum taught him.
