What's a "Saturday Night Live" finale without at least one surprise guest?

Quickly becoming an unofficial "SNL" cast member a la Alec Baldwin, Steve Martin and Justin Timberlake, the great Jon Hamm stopped by Studio 8H once again to appear in the "Lawrence Welk Show" cold open with his "Bridesmaids" co-star Kristen Wiig.

Appearing as Italian crooner Johnny Prosciutto, Hamm wooed the ladies of "The Lawrence Welk Show," including Wiig's typically demented and hilarious character. Normally, the tiny-handed Dooneese has to work twice as hard as her pretty sisters to get some attention on the show, but this time there's something about her that Prosciutto obviously can't resist.

As this is Wiig's last episode as a cast member, we can't think of any better way to wrap up such an impressive "SNL" career than a make-out session with Jon Hamm -- no matter how weird it had to be.

Watch the video above.
