Carl’s Jr. and Hardee’s use their signature humor in ads that promote its Fresh Baked Buns, which debuted in November.

One commercial depicts various situations that play on the phrase “great buns.” Another straightforward ad simply touts the buns’ freshness with detailed shots of the baking ovens.

The CKE Restaurant chains’ new buns are part of a trend this year of upgrading or creating distinction in menu items using buns, from Wendy’s pretzel and brioche buns, to Long John Silver’s Ciabatta Jack Sandwich.
