21 Blink-and-You'll-Miss-Them Easter Eggs That Have Popped Up in The Walking Dead

There are a whole string of Easter eggs that appear to be callbacks to another AMC hit, Breaking Bad, but let's start with the most significant: Walter White aka Heisenberg's iconic blue meth. In the season two episode "Bloodletting," T-Dog (may he RIP) cuts his arm and it gets infected, prompting Daryl to reveal he has a giant bag full of drugs, courtesy of Merle, that might help. When he pulls it out, you can see what looks like Heisenberg's bright blue drug of choice sitting at the bottom of the bag. Did Merle and Daryl know Heisenberg and Jesse Pinkman before the apocalypse?
