Happy Monday, boys and girls! Before I go on vacation, we wanted to get in a Firewall & Iceberg Podcast to discuss last night's awesome "Mad Men," preview the network upfronts, give our thoughts on both "Avengers: Age of Ultron" and its relationship with "Agents of SHIELD," and to review Netflix's "Grace and Frankie."

Also, we're two weeks away from a farewell to "Mad Men" podcast, so start sending in those questions.

The rundown:
