Cameos! Cameos! Cameos everywhere! Billy Porter, Woody Harrelson and Lin-Manuel Miranda all showed up in this week’s “Saturday Night Live” cold open, which sent up this week’s CNN town hall on gay, lesbian, bisexual and transgender issues featuring Democratic presidential candidates. Porter played an M.C. of sorts who introduced the candidates with his typical energy.

The first to take the stage was Chris Redd, who portrayed Senator Cory Booker, the Democrat from New Jersey, who told the audience, “My girlfriend was in ‘Rent’ so yeah, I get it,” a reference to Booker’s significant other, the actress Rosario Dawson. The forum went quickly, with each candidate getting a moment or two — the rare merging of speed dating, comedy and politics. The next to get lampooned was Pete Buttigieg, the openly gay mayor of South Bend, Ind. Buttigieg was again played by Colin Jost, who rarely appears in sketches. In response to an audience member who asked about being “gay in the right way,” Jost said, “There’s no wrong way to be gay. Unless you’re Ellen this week.” This reference was to the daytime television host, Ellen DeGeneres, who recently received flak after being spotted at a football game with the former president George W. Bush.
