When ATC gave a 800 # to a pilot in the air about his IFR flight plan
and his procedures. The pilot probably didn't laugh.

I'm working my way through my IFR training...
Today on the radio "79V switch to 134.0"

Where I dial in 134.0 on the toggle freq acknolege the request
switch to COM2 (Meant to hit toggle)
Annonced that I was checking in....
At which point ground control (from where I'd left 15 min ago)
tells me they don't know why I'm calling..... with laughter.

I realise that this in only slightly funny, but makes me wonder
what is the funnyist thing you have ever heard on the radio?
