I think there should be honourable mention for the ZYZ controller trying to hand off that one plane to ZUL as well... I don't know if you guys remember this but it goes something like this:
"MF2, Toronto Centre, contact Montreal now 127.87"
27-67 for MF2.
Negative, twenty seven, eiiiighty seven.
"27-47, thank you"
"MF2, negative, 27-87"
"Aaah 27-27, thank you, thank you"
"MF2, Toronto, negative......" and on and on for about 2 painful minutes.....
