I often find it pretentious and almost ridiculous to see half hidden lavs on talk shows. There's this soccer discussion round here on German TV every Sunday morning where about 5 guys sit in their chairs and talk. Sometimes the lavs are visibvle but other times the lavs are sort of hidden in their tie knots but stick half out, probably to avoid rustle. Now what is that? A joke? You can see it's a studio situation, there are cameras in frame from time to time, and then they try to hide the lavs in the most half-assed way possible. I mean, if you wanna practice hiding lavs to be prepared for in case Hollywood calls then do it on your girlfriend, and not pretend that a talk show is a feature film.
