Co-worker jokes

If a co worker is sick, is it considered a staff infection?

I really just came up with this joke all by myself, this is a big moment for me.

I was just fired today, simply for telling my co-worker that her hair smelled nice.

I think they are discriminating against me for being a midget.

Co-worker asked me, "If Batman, who is a regular human but with gadgets, teamed up with Superman, who has supernatural powers, and they fought against Iron Man, another regular human with gadgets, who teamed up with Thor, who has super powers, who would be the winners?"

"Your parents when you move out."

I saw an ISIS video, and I got the theme stuck in my head. I was humming it the next day at work when my Arab co-worker said, "soon, my brother."

I think my co-workers are gay

Every time I walk past them in the office, they always whisper "What an ass"
