Thousands of Ways To Annoy People
Based on my daily observations, this is a completely unnecessary list. But in the event you are creatively challenged and need suggestions, here you go:
Announce when you're going to the bathroom.
Ask people to prove everything they say. (e.g. "I'm Bob, nice to meet you..." "PROVE IT!")
Every time someone asks you to do something, ask them if they want fries with that.
Page yourself over the intercom. (Don't disguise your voice.)
