Last winter during the Nato Ex. Joint Winter our local helo sqd got allocated a series of tactical callsigns on the ATO. (Some ex FJ driver at CAOC must have wanted to torment their rotor callauges) They gave them "BunnyXX". ATC offcourse pissing ourselfs while renaming them "Playboy" , "Enegizer" and other assoiciated variants.
We found it funny anyway
