I don't work at Lowe's but I did sleep at a Holiday Inn Express last night. Have you tried putting a broom handle down the disposer and feeling around a bit until you find one of the paddles, and brace the handle against it and GENTLY turn the disposer a quarter turn or so, and then flip the switch? (put something over the drain, cuz if it fires up it might make a sewage geyser for a few seconds before it clears) Lowe's guy, feel free to jump in here if you know any reason that what I said is a bad idea!
Good luck. Hey, check craigslist, inlandempire.craigslist.com. someone in AV is looking for a pair of chickens for $20. Got any culls?
