I will NEVER forget the time I was in the Sheraton in HK & picked up what I thought to be (without my glasses) a bottle of mouthwash--bright kelly green & took a big swig. Yep...it was shampoo!!! I practically brushed the enamel off my teeth trying to get the taste out of my mouth. No, I didn't have bubbles coming out of my mouth all day like in the cartoons but it sure tasted like it.Yuck!
