Sarah Silverman’s locking lips with Joy Behar — yep, it happened live on air … and the audience ate it up!

Check out the clip — guest Sarah told Joy it was a huge deal meeting her on “The View,” when Whoopi chimed in with, “do the goodbye!” … and boom, they went for it.

The clip says it all — but if visuals aren’t your thing, here’s the play-by-play … Sarah leans in, lays one on a ready-and-waiting Joy … then pulls back with her lips sealed like she’s soaking it all in.

Ana Navarro couldn’t resist jumping in — cheekily asking how Joy’s breath was and throwing it back to that bowl of mints sitting in front of her at the Hot Topics table.
