The coolest I've ever seen is the Global Express that Oakley sunglasses owns. It's based out of SNA. The plane is dark grey with the Oakley emblem on the vertical stab and a skull and crossbones on the tail cone. In addition there are fake rivets painted on the fuselage to give it that industrial look that Oakley goes for. Almost forgot, there's a red warning triangle aft of the FO and Capt window. Just like military aircraft that have ejection seats.
Sorry, don't have any links to pictures of it.
