Each person posts theirs as if people's minds are going to be boggled that Nerf guns would be used in a workplace. This video actually uses the CEO (and possibly the only employee) of a web design company talking about Nerf gun strategy as an advertisement for the company. "THAT'S who I want designing my website!" you are meant to say. "This is no boring Joe Schmoe who will give me a beige-colored website. He is a craaaaazy thinker!"
There is nothing more exciting than a guy standing in front of a company logo without a Nerf gun, talking about Nerf guns.
But wait! What about CashLinq, which doesn't just allow Nerf gun fights in the office but actually issues an official Nerf gun to every employee hired? Nobody else would be so crazy as to take fun to the edge like that! Except TerraCycle, and Sudden Impact Marketing, and so many dotcoms in the '90s that it's a standard cliche for a wannabe-edgy company.
The other cliche would be the high-visibility mascot you have to sell when your company goes bankrupt.
