The gunbrella has that roadrunner ACME feel to it. The handle has a subtle curve that looks a bit like a gun handle. Push the button and the real fun starts with a big "BANG" as the umbrella opens. Yours for about $13 here.
Or as Rhianna might say, "You can stand under my gunbrella, Ella ella, ay ay ay, under my gunbrella". Sorry couldn't resist.
