If there were people in the lake I'd say they were bonkers; no one goes in there, although it's happened a time or two in the past...some have ended up as dead bodies feeding the ducks, or the bunyip that lives under the bank. (Google, bunyip)
Any mention of me and Excalibur is legit...if only I had such a sword, I'd wield it well, and for the right reasons...Alas, I'll have to rely upon other edged weapons until Excalibur comes into my possession.
