All These People are Idiots

In a flashback in "The Hitchhiker's Guide to the Galaxy," Arthur Dent attends a party as David Livingstone and Tricia MacMillan attends as Charles Darwin. Tricia tells Arthur he's the first person to recognize her costume and he comments that most of the people who attend parties like this are drunken idiots. She can't hear him, so he shouts that "All of these people are idiots!" just as someone knocks over the record player.
