Do We Have This? Up for Grabs. Happened in older animated films. A character visits a national park and comes along a sign that says something along the lines: "Ol' Reliable - Erupts each day at 16.00". He checks his clock and sees it's exactly 15.59 and 59 seconds when he suddenly gets lifted in the air by a water fountain. Sometimes the geyser can be set up as a trap for the same effect.
Hello, Unknown Troper. You'll need to get known to lend a hand here.
