If this guy asks, 'Don't I know you?' the answer is no

Do you ever get the feeling that you've met someone before but you can't quite place it? Does it make you feel rude for forgetting who someone is when they come up to you and say hi, regaling you with stories of past meetings? Well there's a chance that person might be a prankster. Ed Bassmaster walked the streets of Los Angeles convincing perfect strangers that they had actually met just by going up to them and insisting, "Don't I know you?" It's amazing how many people go along with the gag just to be polite rather than tell Bassmaster, "Nope, wrong person." So now, be even more skeptical when someone asks you this.
