Greasers

A group of greasers was present in Arnie's Diner when Indiana Jones went there together with Mutt Williams.

History
When Mutt hit Joe College, one of the lettermen who also were present in the Diner, another letterman hit him back and pushed him into the groupp of greasers. They took off their sunglasses and got ready to defend him. Mutt took a glass jar from the counter and shattered it on the head of still another letterman, whereupon a fight broke out between the lettermen and the greasers. In the mayhem, Mutt and Jones escaped to the Diner's door.
