Yup... I do it all the time in conference calls to China and Malaysia.
I was a headhunter for the largest private university for quite a few years. I found faculty. There was one guy who used to call me regularly and whine and moan for awhile since I had told him a couple of times that he wasn’t qualified to teach with us.
Every time he called I would give him my spiel and then he would start. I would lay the phone on my desk, bang my head on the desk a few times, and then get up and walk to the kitchen for coffee. When I got back he was still yaking. Everyone thought it was hilarious.
