Berk's Forumvine

I was rewatching season 3 and loved when Tuffnut brought up his Cousin from Stockholm agreeing with his captors (referencing Stockholm syndrome) in "Between a Rock and a Hard Place"

I want to make this thread for all the references you guys notice.

Tag the reference, what it is referencing, and which episode! (I know there are a lot, but I'll let you guys put them all in!)

I really like the penicillin reference Tuffnut made in Buffalord Soldier. Eating moldy bread cured his cold.
Speaking of Buffalord Soldier, the title is a play off of Bob Marley's song "Buffalo Soldier". I loved that reference!
