Not W.C.. Most think it was Mark Twain but he didn't say it either. He was asked if this is the coldest winter he's ever seen and he responded with "no, last summer was" but he was in Paris when he said that. No one's sure who said "The coldest winter I ever spent was a summer I spent in San Francisco", which was probably never exactly said that way.
I just like trivia. Like 'tip', 'to insure prompness' or POSH, 'port out, starboard home' (the best side of the ship passage in each direction.). There's nothing like knowing a lot of usless information.
I also installed the same water heater on my FI36. Good heater!
