Definitely Not Amumu

The Definitely Not skins are of champions wearing a disguise costume but the disguise is obviously mediocre, and everyone knows who it is underneath that costume.

What costume would Amumu wear? The same costume that every sad person would wear: a clown costume! He would wear a frown as opposed to the traditional smile of other clowns like Shaco, his Bandage Toss ability would be handkerchiefs tied together, he would rock an Afro because an Afro on that short guy would be hilarious, and everyone would realize that he's sad underneath because he's Amumu, giving away his disguise with his personality.

I know Amumu already has a lot of skins, but I think a sad clown with the Definitely Not theme is too good not to share. :)

On a serious note, a lot of comedians are really quite sad underneath and use comedy as a coping mechanism. On top of that, they aren't taken seriously so whenever they do want to talk about what is close to their heart, every one thinks it's a joke and the comedian ends up lonelier and lonelier over time. It makes a lot of sense for Amumu, being as sad and lonely as he is, to wear the clown costume.
