Fair question, Bony;

Well, threads at HMT.net are laden with concise technical discussions of the highest order. Even higher when Marv K posts solutions containing elevated mathematics.
Hence, if opportunities to express levity [humorless members declare as 'hacks'] occur, let's just say the badger gets loose. It'd be a fault not directing attention to prime defense exhibit "A" within Off Topic Forum, where Shop Truths, Phrases, Tales; and Outright Lies carries on, via happiest band of miscreants around. No turn goes un-stoned. Some are known to attach musical interludes or topical bits of movie script. Such is the free-for-all known as the internet.
Thank you Al Gore.
