Marge: Barnacle Bill's Home Pregnancy Test? Homer, shouldn't we have gone with a better-known brand?
Homer: But Marge, this one came with a corn-cob pipe!
Marge: [reading from the test box] "Ahoy, Maties! If the water turns blue, a baby for you! If purple ye see, no baby thar be!"
Homer: So, which is it? Blue or purple?
Marge: "If ye test should fail, to a doctor set sail!"
How about the theory that ceramics were first made by Indians and dated back between 25,000 to 8,000 B.C.. This would give you plenty of room to work with. Such as the use of ceramics in ceremonial rituals. Or the development of various techniques used in the making of ceramics over the centuries.
