Ooh, good question.  Originally I was thinking I'd either name "cats" to "dogs" or "dogs" to "cats" to finally put an end to the cats vs dogs debate, but that'd probably just make a weirder debate over which cat is best cat.  Instead, I think I'd rename bears to poohs, so Winnie the Pooh would finally make sense.  Plus, it makes them sound much less intimidating.  Black bear?  Nope, black pooh.  Grizzly bear?  Nope, grizzly pooh.  Panda poohs are especially cute-sounding now.  I don't really have any other reasoning behind it.

For the next poster, if you could experience an event, whether real or fictional, what would it be?  Think of the positives of said event and don't worry about the negatives.  In this particular thought exercise, being a warhero has all the benefits of the heroic act and aftermath, without the negatives of war and psychological turmoil.
