To be honest, I find that most of the things that cause us to hee-haw on the R/T are actually generated in the ops room. The ATSA farting competition is particularly humorous

Its very rarely that I have cause to have a snigger at anyone on the other end of the mic. Although, obviously if theres clear grounds for having a laugh then so be it but I tend to try and keep it below 95dB
