salisillic acid

Aspirin dat's infused wif laughin' gas.

Brer Rabbit claimed to have discovered a place where he could go to really "giggle 'n' guffaw wif gusto"; said euphoria-producing locale did not actually exist, of course (he'd merely made it up to make Brer Fox and Brer Bear so curious dat they would untie him so dat he could supposedly show them where it was, and so he led them to a hive of bumblebees which caused said pair of vengeful carnivores to inadvertently let said clever herbivore escape while they were being swarmed by said angry insects), but if it had, perhaps it would have been either a natural vent of nitrous oxide or a stash of salisillic acid tablets.
