A few of the pilots I flew with at my previous airline would actually listen out on the PA for crew making PA's "we remind you to please remain seated blah blah" and would actually purposely tap the brakes on the way into the gate...
One of my favourites re this issue that I used to use was "We ask you to please remain seated until we have reached our gate at the seatbelt sign has been turned off. Never before in history has a passenger beaten the aircraft to the gate - please dont be the first to try"
