Coconuts: My Gawd, are there really people out there who collect that stuff, never read the things but collect them anyway. Yar pulling our leg captain eh!
The Captain jesteth not, trust me.
I have acquaintances who collect safety cards as well as other things off aircraft. I absolutely refuse to take safety cards off aircraft so they don't get any from me (although I will happily oblige with copies of inflight magazines and other things obviously intended to be taken away.)
