Adam Sandler sings a tribute to Lorne Michaels in sweet 'SNL50' sketch

For 50 years on "SNL," "none of us were allowed to use the little bathroom in Lorne's office."

So sang Adam Sandler, "SNL" cast member from 1990-95, during the sketch comedy show's 50th anniversary special on NBC Sunday. The comedian, actor and sometime singer returned to Studio 8H to sing a ballad all about the half century "SNL" has been on the air, with a few choice jokes thrown in. In the ballad, titled "50 Years," Sandler paid tribute to the series and Lorne Michaels, its creator, as only he could.

"Fifty years of your sketch killing it at read-through, and finding out they didn’t pick it because the host didn’t want to take off his shirt," he lamented. "Fifty years of writers seeing Spielberg at Lorne’s monitors. Not laughing at one of their sketches that he obviously hated. Fifty years of those same writers then getting wasted at the afterparty, and loudly telling everybody that 'Jaws' was overrated."

Jack Nicholson introduces Adam Sandler in rare public appearance

Oscar-winning actor Jack Nicholson, 87, made a very rare appearance in Studio 8H to introduce Sandler's ballad. The actor made his last film appearance in 2010, but was on the "SNL" 40th anniversary special back in 2015.

Even Sandler knew the moment was special. “Let’s hear it for Jack, baby! Jack baby, out tonight!” Sandler said before he sang.
