At Home Depot we know the Christmas season has arrived when all three of these things happen: 1. Our first shipment of Christmas trees arrives 2. Our music vendor starts playing nothing but Christmas carols 3. And someone asks for a male-to-male AC adapter. The M - T - M adapter is used when you decided to drink a whole case of wine before hanging the Christmas lights because no one is this stupid without chemical assistance. You put up the first strand of lights, plug it in, then put up the second strand of lights without checking which end you're dealing with. Next thing you know, the female ends of both strands are right next to each other and you can't plug them together. Instead of running an extension cord between the female end of the first set and the male end of the second (good), taking the second strand off and putting it back on correctly (better) or plugging all of the lights together before you try putting them on the tree (best), off to Home Depot you go for a male-to-male adapter. We don't have them. No one else has them. I'm pretty sure it's illegal to make such a thing. And even if it wasn't, you shouldn't use such a thing because you'll either kill your cat, kill your kids, or burn your house down. Do you really want live 110-volt electricity poking out the top of your Christmas tree? Do it right. Doin' it wrong ain't worth it.
