Their first meeting
Over the last nine seasons of The Big Bang Theory, we've loved watching Sheldon and Leonard's bromance blossom, and their bond only seems to grow stronger as the years pass.
Let's take a look back at the tumultuous—but always entertaining—friendship of these brainy pals.
Although fans didn’t witness the guys' first meeting until Season 3 (Episode 22, "The Staircase Implementation"), we learned that Leonard was introduced to Sheldon after looking for a room to rent near Caltech. And while he was warned by former roommates and neighbors of the theoretical physicist that Sheldon was crazy, Leonard proceeded through the extensive interview process and roommate agreement before eventually moving in.
Watch The Big Bang Theory on Thursdays at 8/7c on CBS and CBS All Access.
