The guys enjoyed a night out Tuesday at Bone Lick BBQ. The acclaimed house of hog is quite a hit with visiting celebrities. Jack Black stopped by while he was in Atlanta filming "Goosebumps" and Ashton Kutcher and Mila Kunis dined there while on a 2013 road trip.

Hamm is no stranger to Atlanta. The "Mad Men" star was here a couple of years ago filming "Million Dollar Arm." 

"Joneses" is being directed by Greg Mottola ("Superbad") and also stars Gal Gadot and Isla Fisher.
