Marc Summers made dreams come true Tuesday afternoon on the streets of Los Angeles ... by playing a little game of "Double Dare" with a TMZ photog.

Our guy Jake has a history with the old 'DD' host, having given him a dare on the street last year. But this time it was Summers' turn to deliver the dare ... and he actually went back inside where he was having lunch to fetch a whipped cream pie specifically for the challenge. 

Your 10-year-old self will LOVE this clip.
