In an effort to encourage sober drivers over the Thanksgiving holiday, the Arizona Department of Transportation decided to get silly. Or is that dilly?

Television viewers are likely familiar with Budweiser's latest ad campaign, featuring a court in a vaguely medieval setting. Those in attendance who bring Bud Light receive an enthusiastic reception, with everyone saying, "Dilly, dilly!" Those who do not bring Bud Light are sent to the "pit of misery."

The Arizona DOT sign reads, "Sober driver? Dilly! Dilly!"

In case you're wondering, Merriam-Webster defines dilly as "one that is remarkable or outstanding."

An Arizona DOT spokesman told azcentral.com that the agency often uses pop culture references in its messaging to connect with drivers.
