KIRK: Oh, nothing, just a little scratch.
LORELAI: Looks like a big scratch. Wow, Bactine, Neosporin, Mercurochrome – what’s with all the pharmacologicals?
Bactine: an antiseptic treatment containing lidocaine anaesthetic, first marketed in 1950.
Neosporin: broad spectrum antibiotic cream containing anaesthetic, approved for use in the US in 1971.
Mercurochrome: a topical antiseptic with a dye which stains the wound bright red. First developed in 1918, its distribution in the US was halted in 1998, due to concerns about it containing mercury. Somehow it is still available for sale in Stars Hollow in 2002! It is now manufactured in the US without any mercury.
