At first I thought it was the kid's Levis that made him walk funny... but I later found out, it wasn't what he was wearing, but what he was drinking!

In a 1998 Harp Lager commercial, an entire pub dances up a storm after having a pint or two. The special effects look VERY similar to the Levi's commercial.

The Harp spot can be viewed at www.adeater.com [1]. Go to their film library, search by BRAND (Harp) and COUNTRY (The United Kingdom). It's their "4.3% Irish" campaign.

I wonder what The Ministry of Funny Walks thinks about all of this?
