Serena Williams and Shaquille O'Neal are among the sports stars joining a viral social media trend. Athletes whose careers peaked in the 1990s are posting throwback videos set to the Goo Goo Dolls' 'Iris'. The meme features a slideshow of the athletes' younger selves, asking 'Dad/Mom, what were you like in the '90s?' Williams and O'Neal are prominent examples of this wave, alongside others like Alex Rodriguez, Andre Agassi, Doug Gilmour, Israel Adesanya, Tony Hawk, Ronaldo, and the Manning brothers.

The trend capitalizes on nostalgia for the decade's fashion and culture, including Trapper Keepers and Reebok Pumps. While primarily a fun meme, it highlights how iconic figures from that era remain culturally relevant. The posts often include playful humor, making the '90s feel alive again for a new generation.
