sniper is laughing secretly at pyro struggling to lift a furniture. Pyro is schizophrenic and sees the furniture as a big cande and sniper finds it so amusing he starts to chuckle far away in his tree house that never was found out by his teammates

He thens stops laughing and goes down the tree to make some fresh jarate. After the pissin' session he walks into the base and stretches

"Ay, good one mate!"
