Salma Hayek -- who infamously danced with a snake in "From Dusk Til Dawn" -- absolutely freaked out when a snake interrupted the press junket for "Grown Ups."
The slithery sideshow went down as "EXTRA's" Terri Seymour interviewed Salma (that's her in the green dress) and co-stars Maria Bello and Maya Rudolph about their new movie.
Just listen to the screams ... this may be the funniest thing you'll see all day.
