Samantha Ronson went bananas Sunday night at the Georgica Blue&Cream party in East Hampton when a party girl bumped into her deejay booth, spilling a drink near her turntable. Rambunctious Ronson stopped the music at 2 a.m. to give the guests a lecture on party etiquette. “If I’m gonna play for you, I think it would be common courtesy not to spill drinks on my table,” she yelled. “I thought this would be obvious but apparently not!”
