- "Get that greaser!"
- ―Letterman[src]
A Marshall College Letterman was present at Arnie's Diner in 1957 when a greaser sucker punched "Joe College". After Joe's girlfriend and another letterman struck Mutt back — sending him into a group of fellow greasers — he stepped forth and announced to his associates to "get that greaser!" A gang fight ensued which allowed Williams and Indiana Jones to escape two KGB agents that had been spying on them.
