Socrates

Socrates made a cameo appearance in Lewis and Clark vs Bill and Ted. He was portrayed by EpicLLOYD.

Information on the cameo
Socrates, written as Σοκρατης Sokratēs in Greek, was a classical Greek philosopher credited as one of the founders of Western philosophy. He is an enigmatic figure known chiefly through the accounts of classical writers, of his students Plato and Xenophon and the plays of his contemporary Aristophanes. Plato's dialogues are among the most comprehensive accounts of Socrates to survive from antiquity, though it is unclear the degree to which Socrates himself is hidden behind his 'best disciple', Plato.

Through his portrayal in Plato's dialogues, Socrates has become renowned for his contribution to the field of ethics.

In the movie Bill & Ted's Excellent Adventure, Socrates is one of the historical figures that Bill and Ted recruit to help them pass their history class, so they don't fail and have to send Ted to military school.
