Go long "Cactus!" The callsign will be missed. At least it will not be forgotten. I am sure none of us (at least those of us who follow aviation) will never forget this transmission:
---"Cactus 15[49] turn right 280 you can land runway one at Teterboro."
---"we can't do it."
---"kay which runway would you like at Teterboro?"
---"I'm sorry say again Cactus?"
(Ok, ATC actually said Cactus 1529 at this point but I corrected it for this post).
