Too many gadgets

[andypaul]

I was a friend of mine in his house recently, and he went and stood in the middle of the room and whistled. I said "Are you all right?" He went "shhhhhh" And then he started whistling again. I said "What are you whistling for?" He said "My keys" I said "Your keys?"
He said "yes, when I whistle at them, they let me know where they are" How do they do that? Do they go:"I'm hiding in the kitchen- come and find me!" DAFT! gadgets- blah!

Surely you just look where you last left them
