In the song "Time of my Life" from Dirty Dancing, the song says "so we take eachother's hand, cause we seem to understand the urgency".... and I thought for the longest time that they said "we seem to understand the earth and sea." I thought it might be some kind of earthy, new age, hippie thing about understand nature because they are inlove... or vice versa.. ok maybe I just don't know anything.
