Inflatable hot tub?

The fiberglass ones are always free around here. "come and get it" is usually the header. In-laws have one they made a deck around. Nice remote pump and filter. Just right for the 5 year old to bob around in at about 80. Friend had one whose thermostat failed and it would not stay lit. I got the bright idea of bypassing it and running the gas straight to the heater under it. We'll light it and jut let it warm up and then feather it to keep it warm. So Im under the cuzzi frame with a lighter and im telling him to turn the gas on slowly, he tells me its already on! Wooosh! Knocked me back on my *** and singed my eyebrows. I was laughing so hard it didn't even phase me. That night was one for the history books.
