Billy Baldwin took to Instagram Saturday to look back at his sister’s 1975 Long Island wedding.

The actor shared a snap of his family, including brothers Stephen, Daniel and Alec, posing at the event, which was held at The Riviera in Massapequa.

In addition to commenting on his yellow leisure suit in the photo’s caption (“Don’t ask.”), Baldwin shared that the wedding marked the first time he ever got drunk.

“My dad found me out back throwing up over a railing into the Great South Bay,” he wrote.

Baldwin, who was 12 at the time, noted he’d only had “two cans,” prompting his father to call him a “Two Can Man.”

“Gotta admit,” he ended the post, “...to this day that still stings a little.”
