This guy, along with another guy who looks freakishly like Adam Sandler, appear in All the Way, they appear to be good friends of Ralph, and are even in Ralph's gang, The Gems. I don't he or Adam Sandler look-a-like were ever mentioned by name, but they seem to be at least kinda friends with Richie, as they seem to be interested in Richie's sex life. I beleive they are credited at the end of All The Way as "Pat" and "Cook". I'll include photos just in case anyone recognizes the characters/actors.

I think "Cook" means a cook at Arnold's. IMDB says that role is played by Rick Hurst, who was 28 years old in 1974 and wasn't someone who could fake it as a teenager.

As guess the dark-haired kid is Danny Jacobson as Pat. He went on to be a successful writer/producer on Roseanne and Mad About You.

That seems to leave the red-headed kid to be Jack McCulloch as "Teen."

I'll take it that you're not talking about the same Rick Hurst who went on to play Cletus on The Dukes of Hazzard because neither one of the guys pictured above look even remotely like him.
