Heh heh, when the mic wasn't keyed, I'm sure the controller said "Oh you've gotta be freakin kidding me!"
I remember a busy day working in the tower, we had an aircraft depart and immediately returned due to smoke in the cabin, ARFF called out obviously.
Then, about an hour later, the ATCT tower cab had a small fire in the equipment room, which the airport fire dept went to go help with. Then, while that was going on, we had an inbound RJ with a flaps fail declaring an emergency. Then, just as that RJ was rolling down the runway, there was another emergency return due to smoke in the cabin immediately after takeoff. 4 emergencies within an hour, with 3 at the same time. Busy day...
