Subway ramp on Ghostbusters prem/le. Not a difficult shot but you still have to hit it solidly up one of the steeper ramps in pinball, takes a right turn and travels on subway tracks over the "city," goes down under the playfield like a subway going underground, then pops back up in your inlane. Wicked shot.
Richard & Mortimer portal shot is a neat one, too. A long shot at the top right, travels along the back, gets to the garage and "teleports" down to your left inlane. Clever.
