There's an idiom in US english, "and if you believe that, I have a bridge to sell you", meant to imply that someone is gullible. It's usually what's being referred to when someone is talking about selling a bridge, and is a source of humour when someone actually sells a bridge. It's in reference to the criminal exploits of confidence man George C Parker.: https://en.wikipedia.org/wiki/George_C._Parker https://en.wikipedia.org/wiki/George_C._Parker
