How do you make everyone the same character in game?

I've been wondering how you make everyone spawn in as the same character.?

Delete anything that they might have such as t - shirts. shirts, pants, hats and change their body part brick color to something noobish.

If your not Good at Scripting you may Use Khols Admin V2. All you have to say from there is (Prefix) (Char) (Name) (Username ID) Example. :Char Masterspartin191 1

That would Char Masterspartin191 to be an Guest. OR you could say :Char all 1 Which would Char everyone To be an Guest.
