On Roseanne, Johnny Galecki and Sara Gilbert ended up married, but in real life the costars dabbled in dating before going their separate ways, romantically speaking. Still, that didn't stop the longtime friends (seen here in 1995 and 2008) from reminiscing about the old days – and their onscreen reunion on The Big Bang Theory – when Galecki appeared on Gilbert's The Talk. "I was more nervous about our kiss on Big Bang Theory than I was on Roseanne," Galecki confessed to Gilbert. "You're the only person who can gauge if I'm improved as a kisser over the last 20 years."
