While back descending inbound a CA told me to "dare him..."
"What?"
"Just say you dare me."
"OoooooKaaaaee. I dare you."
Takes off his headset, removes the mic cover and cracks a really loud one on comm 1 over approach frequency. I was laughing all the way through the landing (my leg).
'nother guy had one of those little digital recorders... ground stop in ATL if I remember. Some mainline was whining about something over the freq, so he recorded a choice bit from the cockpit speaker and played it back on ground over comm 1. I was rolling again.
There was a really annoying bump on one of the bridges in PHX- couldn't grease it no matter what ya did. So the one CA clicked the pax mic, "boingggg" as we went over...
