Trivia: Greta handed Clinton (in bed) a mug and after he took a sip, Clinton asked, "What is this - just boiled whiskey?" Greta smiled and replied, "Yeah, pretty much."

Hot toddy is used to help alleviate the symptoms of a cold/flu or served as a nightcap to help facilitate sleep (although it may actually interfere with getting quality sleep). (00:51:30)
