Billie Eilish tried her best on 'SNL' but Kate McKinnon can make anyone break

Don't blame her. Who could stand close to Kate McKinnon, acting silly and not break out into hysterics?

Eilish, the evening's host and musical guest, was supposed to break character and burst out laughing during their ad for a hotel, but the Saturday Night Live veteran made it her mission to get her. The mission was a resounding success.

Eilish and McKinnon are the same person and they are both at the Business Garden Inn & Suites & Hotel Room Inn. It's not a nice hotel, and there's no positive spin on the rundown of accommodations and amenities. Neither woman tries.

Eilish is focused on getting her lines right and not cracking up. It's difficult as she injects added weirdness into her performance and turns it on her co-star. There was an oddly timed turn here. The sketch doesn't fall apart. Eilish can't help the laughter, but the two see it through to the end, and our day is enriched with laughter.
