The most annoying thing ever in the morning when some stranger calls at 5 AM and says to you...

"You Mother******!!"

How did I know?

Someone called earlier at 5, well I was sleeping but my brother was the one who answered it. He replied back

"Your a mother****** too!! How dare you call early in the morning?! Huh! you jerk! Rot in hell you piece of sh*t!"then he hunged up. My brother's mood in the morning is not very good coz he only slept for 3 hours I think~
