Cordex can confirm this actually happened today.
If while wandering through the NRA Convention and you happen to go around a random corner, look up and see Heckler & Koch, turn the Brain Filter ON.

I blame Larry Correia.
Had a great time there and hanging with Cordex. Thanks for Lunch !! Next time I buy.
