Soo, there's a story behind it. Let show it in this short chat:

-Lesser - "NO, not yet. You can go after umberling let you."
-Brutus - "BUT masteeer! It's not fair!"
-Lesser - "Oh yes, it is. You were to lazy to think about a good disguise, this little guy had better costume than you did, and he doesnt even has arms! Also, it's not only your punishment, but mostly his reward, so be a bit patient and let him enjoy it."
-Brutus - "Oh come ooon, you enjoyed my incubus costume! I wasn't lazy I was creative!"
-Lesser - "You were just naked, that's NOT creative. Now stop your bitching or I'll let them all get to your ass!"
