When you're on your way home from a long day of work and the sky opens up on you, sometimes you just want to shoot someone. With the Howdah Pistol umbrella, you can pull the trigger and not, you know, go to prison or something.
Personally, I tend to imagine that my umbrella is a extensible stun baton, but pretending it's some kind of wacky pistol seems like a viable alternative. And as cool as push-a-button-to-extend umbrellas are, pull-the-trigger-to-extend umbrellas seem just slightly cooler. Almost cool enough to out-weigh the inherent awkwardness of carrying an umbrella.
