While ferrying workers back and forth from an offshore oil rig, the helicopter lost power and went down. Fortunately, it landed safely in the lake.
Struggling to get out, one man tore off his seat belt, inflated his life vest, and jerked open the exit door.
"Don't jump!" the pilot yelled. "This thing is supposed to float!"
As the man leapt from the helicopter into the lake, he yelled back, "Yeah, and it's supposed to FLY too!"
