The busboy who is suing Lindsay Lohan -- alleging she was drunk when she crashed her Mercedes into his van back in 2005 -- may have found the proof he needs. TMZ got a hold of Lindsay's bill from the Ivy restaurant, where the now-rehabbed had been dining with chums. The bill clearly shows that the party of five ordered four Ivy Gimlets -- a strong vodka/mint drink, but there's no way of knowing if Lindsay, who was 19 at the time, partook of the tasty cocktails.
