How long would David Koechner and Jessica Biel have to be stranded up on Mount Kilimanjaro for Biel to consider having sex with him? These, and other riveting issues, are discussed in Gotham's latest web video for Denny's 'Always Open' series.

The videos, hosted on College Humor, feature Koechner in funny one-on-one interviews with celebs -- this year's lineup includes Biel, Maya Rudolph, Christina Applegate and Andy Richter -- while they chow down on Denny's food (we're assuming Biel doesn't partake in Denny's mozarella-sticks-grilled-cheese).

The conversations are unscripted and filmed at a real Denny's, and filed by Jason Bateman and Will Arnett's "DumbDumb Productions."
