Memorable Oscar Moments

Tom Hanks needed a drink after realising that he'd just outed an old classmate and teacher as gay during his 1993 best actor acceptance speech for Philadelphia.

The slip occured in front of an audience of millions and resulted in unwelcome celebrity for high school drama teacher Rawley Farnsworth and former classmate John Gilkerson.

(Apparently, Hanks had already warned the teacher about the prime-time speech).

The revelation inspired the 1997 film In & Out, starring Kevin Kline as an English Literature teacher who is outed by a former student in a similar way.
