AVAM has a lot of unique art in this exhibit, but let's not kid ourselves. The real appeal is the whoopee-cushion bench, which provides unlimited farts. If you insist upon some "sophisticated" art for your money, that's possible too. What Makes Us Smile?, co-curated by Simpsons creator Matt Groening, does not just make you happy, but forces you to ponder what makes you happy and why. AVAM has a wall full of comics, political statements, eerie circus sculptures, and provocative paintings galore. Visit the photo booth on the third floor to add your smile to the mix.
