Flaming Lips singer Wayne Coyne thinks he’s come up with a bright idea to make light of the panic caused when he accidentally packed a dummy grenade in his carry-on, causing a terminal shutdown at Oklahoma City’s airport. He’s signing gold-painted, fake grenades selling for $50 at Dwelling Spaces, which just opened inside Coyne’s Womb Gallery in Oklahoma City. A rep for the shop tells us the idea was a “collaborative effort” and is trying to make “light of the situation.” Just don’t pack them in your luggage.
