Four quick ones

• Computer keyboards have those little bumps to help touch-typists know whether they have their hands positioned properly. (They have a rude nickname.) Why hasn't the same idea happened on keyboard instruments such as pianos? Furthermore, by way of analogy with ergonomic computer keyboards, couldn't someone devise a curved piano/organ keyboard to make it easier for the musician to reach the very high and low notes?
• Citigroup and Morgan Stanley to merge former rival brokerage services. The new company is going to be called Morgan Stanley Smith Barney, but I think it misses an opportunity to resurrect an old brokerage unit name associated with Morgan Stanley and call it instead Dean Witter Reynolds Smith Barney. Or was the Dean Witter marque too downmarket? I know it is probably too late to cancel the order for office stationery, but still.
• If we do successfully downsize our military operations in Iraq, maybe we can take some of those remotely controlled Raptor drones and set them up with rocket-propelled paintball armament to have simulated aerial warfare. There could robotic convoy of vehicles or something that a second player could control while the first player attempts to splat the target in one particular vehicle, without causing collateral damage.
• Among religious believers, it is often customary to say a prayer before sharing a meal. It seems to me to make even more sense to say a prayer before partaking in intoxicating drink. Bless us, O Lord, and these, Thy libations, which we are about to receive from Thy bounty. One could be more elaborate, with some mention of avoiding drinking and driving or whatever. Perhaps some public service spots could help to popularize this new custom.
