Melissa McCarthy, Kristen Wiig, Kate McKinnon and Leslie Jones sat down to plug their new "Ghostbusters" movie on "Kimmel." They were pleasantly surprised when the old band of busters (Bill Murray, Dan Aykroyd, Ernie Hudson and Annie Potts) came out to support them and reminisce about the old days. Both casts did some cutesy dancing to the theme song and chatted about the film's legacy. 

Before the old cast made their grand appearance, the ladies dismissed angry backlash against the new movie:

Leslie lightened things up and talked about how she is on the hunt for her ideal man:

The old cast arrived on the scene and commenced forced hugs:

Both casts combined into an adorably awkward dancing blob as Ray Parker Jr. played the original theme song:

Bill Murray gave his official endorsement of the film, though implied he thought the beginning was a bit rocky:

The old cast took their turn chatting with Kimmel. They talked about stealing things around NYC while shooting the original film:

Even The Stay Puft Marshmallow Man wanted in on all the old fun. Bill Murray really enjoyed rocking the heck out of him as Potts rolled her eyes:

Finally, the squad took a look at fan tattoos and showed off some of their own:​

Maybe all of this was a grand ploy to convince fans that the movie will actually be good, but isn't that every late late night appearance? Plus, it was darn cute.
