Back in 2013, McKinnon appeared on DeGeneres's show dressed as the funny talk show host.
And now she's back! Once again, she came out looking like DeGeneres's long-lost twin.
Then she dived into an Ellen-esque monologue, complete with a charming story about a puppy.
And somehow goats were thrown into the mix.
And it wouldn't be a true Ellen impersonation without a cool dance break, right?
Look at these two basking in their loveliness.
Please have Kate on every week, Ellen.
