There’s plenty of news coming out of Apple’s WWDC conference event–and plenty of corny jokes being made from the Apple execs on the stage–but to introduce the event, they brought in a few ringers to ensure that the jokes actually landed.

To pull that off, they began the event with a video starring Bill Hader as “David LeGrey,” a Birdman-style visionary producing the event’s high-profile opening number. He assaults an Angry Bird, and nearly gets a Goat Simulator stand-in goat killed before confronting Veep’s Matt Walsh–as a floating “angel investor”–and Community’s Danny Pudi, who performs a dramatically auto-tuned rap number. When things go bad, though, the more traditionally stripped-down Apple keynote stage setup returns–prepping the area for Tim Cook and Craig Federighi’s big-time dad jokes.
