They are the advance team from the Mother Ship. They will keep you on the phone and as you are listening to their timeshare pitch, they will zap your brain through your ear with thought-controlling high energy beams. They beamed up my cat last night. I told him never to pick up the phone. Besides, without opposable thumbs, you won't be able to hang on the line anyway. Now he is gone. Alas. I hope they leave my hamster alone. And my dog.
This is not true they are not from the mother ship but it is true that they cannot be trusted talking to your cat. Unless you are tired of the cat. Beware they will convert your cat to their ways and it will divulge your secrets. This is MLM without the rewards. The dog is safe due to his loyalty and breeding. They will eat the hamster.
