After mentioning Sunday's New York City Marathon, Rock went on to joke about why he thought the Boston Marathon was so "scary":
"That was probably the most sadistic, frightening terrorist attack ever. Just think about it. 26 miles. 26 miles is a long drive. If you call up one of your friends, 'Hey man, I need you to pick me up,' 'Where you at?' [and he says] '26 miles away' you better get Uber."
The 49-year-old comedian then switched gears with a bit about how he'll never visit the new Freedom Tower after 9/11:
"I am never going in the Freedom Tower. I don't care if Scarlett Johannson is butt-naked on the 89th floor in a plate of ribs. I'm not going in there."
As Uproxx noted, the monologue was divisive among viewers, but not everyone was offended. Cast member Pete Davidson, whose father was a firefighter who died on Sept. 11, tweeted support for Rock on Sunday:
Chris Rocks monologue was brilliant!! I'm not offended at all. Funny is funny!!
