Welcome back to Mailbag, a series about the sometimes weird, sometimes fun stuff we get in the mail. To commemorate Silicon Valley returning to TV, HBO sent us a box full of Pied Piper swag, including a Pied Piper T-shirt, mug, mousepad, and tiny Thomas Middleditch bobblehead. They did not send us a Pied Piper jacket, unfortunately, which feels like a real missed opportunity.
