Three jocky, well-coifed men pal around in a beat-up bar. Each picks up an instrument for an impromptu jam session. Cue music (“Viva Viagra” plays).

Director: Cut, cut. Who needs this stuff? I use oysters. They’re a natural aphrodisiac.

Actor 1: You going to the Island Creek Oyster Festival this Saturday? Couple dozen half shells. Beers from Harpoon. And chefs from Lineage, Green Street Grill, and KO Prime are cooking.

Actor 2: Ooh! Mitch and I are going. The Heavyweights are playing, too. L-u-v them.

Director: Sounds stimulating, boys. What’s the catch?

Actor 1: No catch. All the money’s going to the Island Creek Foundation. They’ll hand it over to local charities like Crossroads for Kids.

Director: A good cause and a dose of nature’s Viagra? Shucks.

Island Creek Oyster Festival, Saturday, September 20, 4-11 p.m., at Duxbury Beach Park, 435 Gurnet Road, Duxbury (781-934-2028 or islandcreekoysters.com).
