What's the most stress-inducing way to propose marriage? Well, you could ask someone to marry you in front of a huge audience at a major sporting event. Or you could ask someone to marry you during a live television broadcast. The second option is the one that's attempted on 'Parks and Recreation' (Thu., 8:30PM ET on NBC). As you might expect, it doesn't go that well.

[Spoiler alert.]

Mark (Paul Schneider) wants to propose to Ann (Rashida Jones). In her typically helpful way, Leslie (Amy Poehler) suggests that he do it during a live telethon that she's hosting on local TV. Unfortunately, Ann then tells her that she's losing interest in Mark. Will Leslie be able to stop the proposal in time?
