The Monkey is a novelty dance, most popular in 1963. The dance was popularized by two R&B records: Major Lance‘s “The Monkey Time“, and The Miracles‘ “Mickey’s Monkey” both Top 10 Pop hits released during the summer of 1963.
The monkey is often referenced on the animated series Johnny Bravo (in every theme song in addition to many times in the actual show), although it may be a completely different dance. The tv series The Simpsons also referenced the dance at least twice (in seasons 4 and 8). The thrash metal band Exodus reference the dance in their song “The Toxic Waltz” (from Fabulous Disaster) with the lyric “Used to do the monkey, but now it’s not cool”.
