One of the local CFIs did the same to me last winter when on downwind in a PA34.
"Bardufoss TWR, guess who"
Ah, caramba! This is too good to be true i say to myself, and hit the master off button on the light control panel. (kills ALL airfield lights)
And I say with a giggle: "Guess where"
Ahh, good one this.
.......just one tiny problem: I had in my excitement forgot that there was more then this aircraft under my control, namely a P28A from same company on taxi to parking. He found himself in pitch black, and started yelling accordingly on the freq.......
Oooops......
