This Bud Light commercial from 1995 (it was the first in a series of commercials) made the expression, “I love you, man” part of popular culture.
The thing that made the commercial so hilarious and compelling, at the time, is that you didn't hear guys say “I love you” much back then. So it sets you up. It begins with a guy who is a bit choked up, opening up to his dad in a way which, well, guys just didn't.
