Upon discovery of some sandstone deposits in a dried-up river, Mr. Watson questioned Sherlock Holmes on how he could be so sure it's sandstone.

One day a blonde is driving down the highway..
Along side a dried up river. Then she notices another blonde rowing a canoe in the dry sand. Angry she pulls over her pink Hummer hops out and starts screaming " It's because of idiots like you that people give blondes such a bad name! If I could swim I'd go over there and kick your ass"
