Comedy Central is amping up excitement for its upcoming roast of James Franco by releasing preview clips of the previously taped program online.

In one clip, Sarah Silverman calls out fellow roaster Jonah Hill for his yo-yoing weight, joking that the actor's 50-pound weight gain for his role in Martin Scorsese's "The Wolf of Wall Street" was necessary because "producers wanted the character to be a Jonah Hill-type."

"On a scale from 1 to 10, do you own a scale?" Silverman asks an in-stitches Hill.

Another clip features comedian Nick Kroll skewering Andy Samberg, first complimenting his looks and career success then zinging his association with his onetime "Saturday Night Live" BFF.

"Andy, remember when Justin Timberlake would take your calls?" Kroll asks.

The full roast airs on Comedy Central tonight at 10 p.m. The show will also be available for free livestreaming on comedycentral.com, Comedy Central's mobile and tablet apps, and the CC:Stand-Up app on Xbox 360.
