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

~2 yrs ago on takeoff out of BED, tower calls us, "Warrior 10J, hanscom
tower with a request."

"Tower 10J, go ahead," we reply.

"When you cross the departure end of 11, look off to your right and tell us
if you see a kangaroo anywhere."

Long pause. We look around. "Um, negative kangaroo."

"OK, thanks 10J."

Never did find out the story behind that one...
