It most certainly was! The episode is titled Selmas Choice. Deciding she wants to have a baby, Selma practices by taking the kids to Duff Gardens. Bart gets stuck on a roller coaster, while Lisa gets sick after drinking the water on the "Little Land Of Duff" ride, which is a major Small World rip-off, with all the little dolls drinking duff beer! There's also the Duff LIght parade, featuring the Statue Of Liberty, which happens to be drinking a beer. They also have the Seven Duffs (instead of Dwarves), includint Tipsy, Queasy and my personal favorite, Surly. It may also be the episode (I can't quite remember) where they try on the "beer bottle glasses" which make whatever you look at appear as it would after getting drunk. Needless to say, someone looks at Selma with the glasses on and see's her as beautiful, takes the glasses off and... AHHHH!
Anyone catch the much-advertised season premiere of the Simpsons, featuring this great line from homer, who was taking his fugitive mom into hiding:
"I'm going to hide you where there's nobody around for miles and miles... Disney's California Adventure!"
By the way, brown bear... very nice family photo!
