Old geezer read too many books and listened to too many other old geezers to know that this thing he's doing is ineffective, and only serves to make you disinterested in what he wants to say, since its too much of a try-hard attempt. There are much more subtle things you can employ (Sarcuck forces his british accent, for instance, and guillible fucks don't notice, but its effective, for instance).
Still, i'd rather watch his head bob back and forth than listen to Vee's shrieks and quirps, for example. That guy needs to bench quickly, but I doubt that someone who lives on neetbux and tricks his audience as a doctor wants to stay ten feet away from a barbell.
