You guys with your photoshop theories are drunk.
1. they don't drive out of a dam, have a look - there is a bridge across the dam.
2. there is no ocean - its just the edge of a "tidy" dam.
3. are you telling me the cabin shot where the camera looks left and right at dumb and dumber is not real. - or when it is about 10 ft off the dam and they are clearly hanging from the skids
4. there ARE ripple marks on the water from rotors.
All this stuff is academic anyway - they are just a pair of dumb arse lebos and the pilot should be shot for just hangin with lebos.
"BROTHAAAR - woooo"
