Looks like it came from a cask of Thunderbird! (Known from my fraternity (TKE: the original animal house!) college days of the 60s!)

If your taste buds are shot, and you need to get trashed with a quickness, then "T-bird" is the drink for you. Or, if you like to smell your hand after pumping gas, look no further than Thunderbird. As you drink on, the bird soars higher while you sink lower. The undisputed leader of the five in foulness of flavor, we highly discourage driking this ghastly mixture of unknown chemicals unless you really are a bum. A convenience store clerk in Show Low, AZ once told me that only the oldest of stumbling indian drunks from the reservation buy Thunderbird. Avaliable in 750 mL and a devastating 50 oz jug.
WARNING: This light yellow liquid turns your lips and mouth black! A mysterious chemical reaction similar to disappearing-reappearing ink makes you look like you've been chewing on hearty clumps of charcoal.
