Anyone ever had that one classmate/Co-worker who's condesending sometimes?

Like you tell them you and your friends busy, he asks how are you guys busy and you tell him, but he replies with his own list of stuff that sounds like a job for 5 people (sounds like bullsh*t to me..) that makes him busy and rubs it in our face like "aw come on, i can do all that with my eyes closed" and he makes sure everyone in the room could hear it, Not just us.

What had a long day... i need my cat.
