Reminds me of a 70s incident when, if I recall correctly, an F-27 had to make a hasty arrival anywhere after one of the drugged Bengal tigers it was carrying woke up and started strolling around. An ATC wit, thinking the pilot might be pushing to jump the queue, suggested he "put it in the tank".
What, then, would be the appropriate reply to "xxx we have a baboon running lose in the passenger cabin...."?
See ya later, alligator...
