She walks up to the counter and asks, "How much for that pink dildo up on the shelf?" The guy replies, "$25." She said, "I'll take it!" A few minutes later in walks this brunette. She walks up to the counter and asks, "How much for that purple dildo up on the shelf?" The guy replies, "$50." She said, "I'll take it." A while later this blonde walks in. Her eyes got as big as saucers. She walked up to the counter and asked, "How much for that big silver dildo on the shelf?" The guy replies, "$100." She pays him and leaves. In walks the owner and asks how business was doing, and his friend replies, "I sold the pink dildo for $25, I sold the purple dildo for $50, and I sold your THERMOS for a $100."
