According to TVLine.com, David will appear as a hotel concierge on the finale episode of the ABC sitcom, and he will be involved in a sort-of-awkward plot line. 

SPOILER ALERT! 

David will be working at the hotel where Jules (Courteney) ties the knot with Grayson (Josh Hopkins)! Why is this so awkward? Well last year, rumors were flying that Courteney and Josh had an off-screen romance after she and David separated. Wow, this Cougar Town storyline sounds that much more enticing!
