I'll put this in English or my knowledge.

1. The character with the clothes is named Derek, I think. He is from the Telltale game The Walking Dead. Telltale also my Poker Night 2.

2. The next easter egg is a picture off the cast from the first Poker Night at the Inventory. The cast there is Max, Strangbad, The Heavy, and Tycho.

The last is another Walking Dead easter egg with a picture of the 2 main characters, Lee and Clementine.

So everything is in english, but the video? -rate
