I thought a baby bull is considered a...bull. I thought a calf was a baby cow, not a bull. So if what I just said was correct, which might not be, then there would be 2 bulls in the pen. Yet, Ian Sane's idea could be right if he was correct about a baby bull being a calf...hmmm. So then what's the answer Swordplay. That is, unless someone else wants to take a wack at it.
Edit: oops, I didn't realize there was a 4th page...sorry.
Edit2: Who makes it, has no need of it.
Who buys it, has no use for it.
Who uses it can neither see nor feel it?
This is kind of an easy one.
