The version I read was
Cessna 123x - we seem to have a bit of a headwind what is our ground speed?
Center - 85 knots
Lear 123LL - What's our ground speed?
Center - 320 kts
Eagle 1 (f15 in full afterburner)- What's our ground speed
Center - 785 knots
Sled 1 (voice sounds like it is in a space suit) - what's our ground speed?
Center - 1850 knots!
-----------------------
the other one is.
"Flight Service this is sled 2 can you give me winds at FL700?"
Flight Service - "And how are you going to get up there?"
Sled 2 - "We are descending to it!"
