Jimmy Kimmel crossed the casting streams of Ghostbusters ensembles old and new, first in his prime time pre-NBA Finals kickoff special and then later on his late night talk show.

The new cast talks about the interweb haters who’ve been having a conniption fit over the all-female reboot, the old cast shares memories, and both cap it off by dancing to the Ghostbusters theme performed by none other than Ray Parker, Jr. himself.

The all-new Ghostbusters hits theaters on July 15.
