Thanks! Great picture, isn't it? It refers to the 1973 ad campaign for Hush Puppy shoes. There was a dog just like that one in the commercial - it was the brand's mascot - and the jingle ended with "Hush Puppies are duh-uh-uhmb." If you have time on your hands, check the link in the comments for the background story by the ad man who crafted the campaign.
Thank you so much. can you believe that I only made that lol last night. Its funny how sometimes and lol will get in FP right away sometimes, and the other times one make um months after you have made it.
