Things That Make You Go Hmmm...

"Things That Make You Go Hmmm..." is a song by American dance group C+C Music Factory. It was released in June 1991 by Columbia Records as the third single from their debut album, Gonna Make You Sweat (1990). The single version features Freedom Williams and Zelma Davis who also appear in the accompanying music video, directed by Marcus Nispel, while female vocals are provided by Deborah Cooper instead of Davis on the original album version. The song was inspired by a running gag on The Arsenio Hall Show, where Arsenio, while allegedly on a long drive, pondered certain thoughts and referred to them as "things that make you go hmmm...."

The C+C song was a success in the United States, reaching number four on the Billboard Hot 100, number 31 on the Billboard Hot R&B Singles chart, and number one on the 12-inch Singles Sales and Dance Club Play charts. It also reached number four on the UK Singles Chart and number two in New Zealand. The song was certified gold by the Recording Industry Association of America (RIAA) for shipments of over 500,000 copies.
