Day two was exhilarating, as three individual world records electrified Rio and the Twitterverse blew up with all of the fast swimming (and drama).

Of course, Michael Phelps and Katie Ledecky are the greatest swimmers in the world right now, and Twitter was lit up after Ledecky smashed her 400 free world record and Phelps’ delivered an incredible 47.12 split.

Perhaps the biggest moment that didn’t have to do with world records was Lilly King‘s finger wag to Yulia Efimova. In a new rivalry that alludes to a bigger picture of corruption and injustice in the sport of swimming, King’s finger wag on national television got people riled up on Twitter.

Check out some of the best tweets from today’s Olympic competition below:

Swimming’s newest #1 fan is Leslie Jones, who was super thrilled with Conor Dwyer‘s 200 free semifinal win tonight.

In what could be the most politically and emotionally charged events of these Games, Yulia Efimova won semifinal 1 of the women’s 100 breast. The Russian, who has been caught doping twice now, was booed after her swim, but Lilly King‘s reaction was iconic. Efimova put up her finger as if to signify her winning her heat, but King, as she watched the Russian on the TV before she herself swam a semifinal, wagged her finger at Efimova. Minutes later, she would swim .02 faster than Efimova and take the top seed going into finals.
