Once upon a time on Skaro, the Emperor Dalek demanded he be clothed so he could look even more intimidating.

I DEMAND CLOTHES, OR YOU WILL BE EXTERMINATED!

The thing is, Daleks don't wear clothes. It's just a fact of nature. Daleks wear armor, and are thus incapable of wearing clothes. Hats, yes, but clothes, no.

Nevertheless, the Emperor Dalek demanded clothes. He wanted to be the only clothed Dalek, and be the most powerful and unique snowflake of all the Daleks.

So he went to the Skaromart Department Store.

The thing is, the clothes section of the department store was on the second floor, and the store didn't have elevators. Only stairs. And Daleks cannot climb stairs.

The Emperor Dalek shot lasers at everything, demanding he be clothed.

I DEMAND CLOTHES, OR YOU WILL BE EXTERMINATED!

Of course, the store was run by Daleks who could not help him climb the stairs, for they were also Daleks who could not climb stairs.

So no one got clothes, and the Emperor Dalek exterminated everything anyway.

And they all lived happily ever after.
