The opening monologue of this week's Saturday Night Live, courtesy of host Kevin Hart, left a bad taste in some viewers' mouths.

To kick off the show, Hart dedicated his monologue to the challenges of parenthood, including a series of jokes about dads' responsibilities versus those of moms. 

"You never heard a kid say, 'I can't wait to get home and play with my mom,'" Hart said as part of his routine. "You ain't never heard that. 'Can't wait for mommy and me time.' That don't exist. Don't no kids say that. All the fun responsibility lies on the shoulder of the father."

Unfortunately for Hart, many viewers on social media didn't react favorably to his views on parenting, calling his routine outdated and sexist. 

"The sheer acceptance of sexism in the opening monologue is saddening," wrote one viewer on Twitter, with another person tweeting, "Does anyone else think Kevin Hart is nothing more an obnoxious, sexist, seriously unfunny (expletive)?"

As for Hart, the comedian celebrated the evening on Instagram, writing after the show, "Amazing night tonight....Major thank you to the cast of @nbcsnl for always welcoming me with open arms. Love you guys!"

Some Twitter commenters also pointed to Hart's recent confessions about cheating on his wife Eniko Parrish earlier this year while she was pregnant, arguing that the comedian's family-man monologue was hypocritical in the wake of his behavior.

"Is Kevin Hart talking about the *difficulties* of playing with your baby?" one Twitter user wrote. "You cheated on your wife while she was cooking that baby for 9 (expletive) months."
