"Things That Make You Go Hmmm..." is a song by American dance group C+C Music Factory. It was released in June 1991 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, 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 US, reaching number four on the Billboard Hot 100, number 31 on the Billboard Hot R&B Singles chart, and number 20 on the Top 40 Radio Monitor. It also reached number four on the UK Singles Chart. The song was certified gold by the RIAA on August 13, 1991, for sales of over 500,000 copies.

AllMusic editor Jose F. Promis remarked that the song took a phrase popularized by Arsenio Hall and made it into "another cleverly infectious Top Ten smash."^[2] Larry Flick from Billboard wrote, "After forging a guitar-driven pop/hiphop sound that is being heavily copied by others, groove clique deftly sidesteps into James Brown-style funk territory. Rapper Freedom Williams tells amusing tales amid retro-horns and percussion."^[3] Penelope Layland from The Canberra Times named it the best track on the album, "with its clever, catchy lyrics and smooth beat."^[4]

Dave Sholin from the Gavin Report stated that writers/producers Cole and Clivillés "have successfully crossbred a unique brand of rap and melody that's taken them on back-to-back trips into the Top Ten. This third entry maintains their infectious rhythm, strengthened by a title that will keep audiences hummmmin'."^[5] A reviewer from Music & Media wrote that "the secret behind the success of these dance/pop providers is the good hook in their songs. This time it's the saxophone part, which is repeated after each line."^[6] David Quantick from NME said, "The old C&Cs have blown it this time with a very ordinary sort of tune indeed that doesn't so much fail to stay in the memory as break the doors down, steal the car and drive to Birmingham."^[7]

"Things That Make You Go Hmmm..." proved to be a major hit on several continents and remains one of the group's most successful songs. It soared to the number-one position on both the Billboard Hot Dance/Club Play chart in the United States and the RPM Dance/Urban chart in Canada. In Europe, the single entered the top 10 in Finland (10), Ireland (9) and the United Kingdom. In the latter, it peaked at number four in its fourth week at the UK Singles Chart, on July 21, 1991.^[8] Additionally, it was a top 20 hit on the UK Dance Singles Chart, as well as in the Netherlands (19), Sweden (14) and Switzerland (15). In Oceania, "Things That Make You Go Hmmm..." hit number two and six in New Zealand and Australia, respectively. On the US Billboard Hot 100, it peaked at number four. The single was awarded with a gold record in the US, after 500,000 singles were sold there.

The accompanying music video for the song was directed by German director Marcus Nispel. It features silhouetted animation of dancers jumping and dancing in front of a white background, with a stage visible, but also in silhouette. The story of the song is also interpreted with black and gold cut-out animation.^[9]

Australian music channel Max included "Things That Make You Go Hmmm..." in their list of "1000 Greatest Songs of All Time" in 2013.^[10]

British girl group Stooshe covered the song and released it in 2013 as a B-side to their single "Black Heart", under the title "Things That Make You Go Mmm". The single reached number three in the UK and number four in Scotland.
