Pied Piper, it's Congress calling.

HBO dropped a new trailer for the sixth and final season of "Silicon Valley," which finds Richard (Thomas Middleditch) heading to Washington, D.C. to testify about the security of user data.

It's an echo of Facebook founder Mark Zuckerberg's hearing before Congress, but much, much more awkward.

"He looks like a child in a messy custody hearing," says Gilfoyle (Martin Starr) as Richard blunders his way through testifying.

“But you don’t feel sorry for him,” replies Dinesh (Kumail Nanjiani). “You just want him to go away and not have any parents at all.”

But Richard remains undaunted (even when his request to pace goes awry). He promises to create an "internet of the people, by the people, and for the people."

Some behind-the-scenes drama has dogged "Silicon Valley" when cast member T.J. Miller abruptly left before Season 5. Miller called the show "one-note." The cast and crew fired back that Miller often behaved unprofessionally on set and that "T.J. wasn't Lebron [James]."

Showrunners Mike Judge and Alec Berg have previously indicated that they expected the show to run six seasons.

“'Silicon Valley' has been a career and life highlight for us,” they said in a statement. "We’ll miss it desperately, but we’ve always let Pied Piper’s journey guide the way, and Season 6 seems to be the fitting conclusion. We are forever indebted to our incredible cast, crew, and partners at HBO. At a certain point, there’s only so much we can do to make the world a better place.”
