Houston Texans star J.J. Watt and future Philadelphia 76ers player Ben Simmons made their guest appearances in Jimmy Fallon's "The Tonight Show" last week.

Rolling Stone reported that Jimmy Fallon and Houston Texans star J.J. Watt engaged in a showdown of Egg Russian Roulette on last Friday's episode of "The Tonight Show." In the game, they each get to choose an egg and smash it on their forehead.

The three-time NFL Defensive Player of the Year was able to pick the right egg on the first round. "The Tonight Show" host, however, was not as lucky.

In the second round, J.J. Watt got splattered by his choice of egg. Moreover, the Houston Texans star decided to eat the raw egg. "The Tonight Show" host lost when his second choice was also a raw egg.

"You can't eat raw egg," Fallon told Watt. "What are you -- Rocky?"

Last Tuesday, LSU forward and future Philadelphia 76ers player Ben Simmons guested on Jimmy Fallon's "The Tonight Show." After working out with the Sixers, he got another taste of Philly on national TV.

According to NJ.com, Simmons ate his first cheesesteak from Philadelphia on live television, courtesy of Dalessandro's. Meanwhile, he tried to debunk rumors that the 76ers will be choosing him - urging fans to wait until reports confirm on Thursday.

He is also being compared to NBA Finals MVP LeBron James. Simmons admitted that he has become friends with the Cleveland Cavaliers star.

"Whenever I need advice, I call him," Simmons said. "He's been through a lot. He's been through a lot of things that I'll probably go through so he's probably someone good to go to."

Apparently, it is still unclear whether Ben Simmons will be playing with the Philadelphia 76ers. Sixers general manager Bryan Colangelo has previously revealed that they have tried to schedule a workout with Simmons earlier this month to no avail.
