Of course, to avoid getting stuck in that convo with someone you dislike or feel uncomfortable around, don't be passive, be proactive. Do not let them direct your interaction on their terms, do it on yours. Ask a Misdirection Question--something too difficult to answer quickly--e.g., 'What's Congress up to?' or 'You ever learn any cool science?' When you ask the question, don't make eye contact, keep moving and get out of there. Do not wait for a response and deny ever asking it. Repeat these actions until you are never again spoken to by that individual (about four times).
Eugene MirmanOh, Hello. I'm Eugene Mirman, and I'm here to introduce my special. It's called An Evening of Comedy in a Fake Underground Laboratory.
Eugene MirmanFor a short period of time, I was like, I have these jokes and if people get them, they get them. And then eventually, I was like, Oh no. It's absolutely my job to convey to people why what I think is funny, is funny. The whole point of standup is to get the audience to understand your weird point of view.
