Before he could tell Serena what was on his mind Yami saw Serena's face. Confused by it, he looked in the direction she was and stopped dead in his tracks and stared. Never had he ever had to witness what he had just seen right now. And now he could not unsee it for the rest of his life. All Yami could do was bite his own lip- nope nevermind he also had to cover his mouth and look away. He too was on the verge of laughing and about to fail. 

Marik as soon as he saw what was before him could not stop himself a giggled. This he had to say was new for him. "Odion?...what are you wearing?" He asks.
