Seeking friends for funny/dangerous situations

Safety Not Guaranteed: "Three magazine employees head out on an assignment to interview a guy who placed a classified ad seeking a companion for time travel."






Seeking a Friend for the End of the World: "As an asteroid nears Earth, a man finds himself alone after his wife leaves in a panic. He decides to take a road trip to reunite with his high school sweetheart. Accompanying him is a neighbor who inadvertently puts a wrench in his plan."

I guess there's no classified ad in the Steve Carrell one, but the title is phrased like the start of an ad.
