"Please let it be a joke"
I'm convinced that there are many people who would gladly light up one of those candles purely for fun, out of sheer curiosity (does it really make it smell like a Mc D hamburger) and, for some, for simple convenience (it's a candle).
I would be part of the curiosity crowd, then I switch to convenience. Only for the one, though. Scented candles are not really my thing.
