'Saturday Night Live' is back with a new season, new cast members and a new President Joe Biden impersonation. James Austin Johnson opened the show with his take on an exasperated Biden addressing the country about his infrastructure legislation and the general state of everything. "Broadway's back, that's exciting right?" he said to thunderous applause. But quickly snuck in: "So is the Taliban. So, win-some, lose-some." Guest performer Jim Carrey famously appeared as the president last season. The iconic late-night series also paid tribute to the late Norm Macdonald during its season premiere by showing footage from his stint hosting "Weekend Update." "Tonight, we thought we'd turn the last few jokes of 'Update' over to Norm," Colin Jost said. 📸: Will Heath, NBC
