Once the nagging insurance salesman Ned Ryerson in Groundhog Day, Stephen Tobolowsky seems like he will be a thorn in the side of Pied Piper in the latest season of Silicon Valley as shown in this trailer. 

Thomas Middleditch/Richard Hendricks goes through a bit of an early Steve Jobs phase as well.

Catch the premiere next month on Sunday, April 24th at 10PM on HBO.
