My best memory of this movie came during the summer of my 1st job out of college. Eurotrip came out my senior year of college. A buddy and I were working a crappy 2nd shift QA job in a manufacturing plant right out of college. We both had 2 way walky-talky radios on the production floor to communicate with production supervisors and maintenance guys although we worked in entirely different areas of the floor and never saw each other. Everyone with a radio had their frequency set to channel 1. The name of one of the maintenance guys on our shift was conveniently named Scotty. Once a week during that summer my buddy and I would wait until the early evening to make sure top management had gone home for the day, set our radios to channel 3 and then have this exchange:
Hey, this piece of equipment broke down
Did you call Scotty to fix it
Yeah, Scotty doesn't know how to fix it
What? I didn't hear that
Scotty doesn't know
The person with the italicized lines would start singing Scotty Doesn't Know over the radio and could clearly be heard within 10-20 ft radius of the other person's radio. The person not singing was responsible for doing a jacked up dance while the other guy was singing. About a third of the 2nd shift folks were recent high school grads or college kids working there for a summer job before heading back to college. All of them enjoyed the Scotty Doesn't Know reference and sometimes would join in on the dancing if their supervisor wasn't around.
