Betty White finally hosted "Saturday Night Live" last night -- and she killed it.

The 88 year-old star made sure to thank Facebook in her opening monologue -- since a campaign on the site was a huge reason why she got the hosting gig in the first place -- and joked "I didn't know what Facebook was, and now that I do ... it sounds like a huge waste of time."

In case you missed it, the whole episode is online over at NBC.
