That time the Matt Moore super fanboy left The Huddle was honestly probably top 3 panther fan happy moments for me. When Manning, Jr. picked off that ball against the Rams in OT was pretty wild. And when we needed some weird formula to make the playoffs by point differential or something and they were showing the Panthers game simultaneously with I think it was Green Bay was pretty cool just because that was long before I had Sunday Ticket and I never got to see Panthers games on TV in California.
Guardians edges out Avengers IMO simply because it's the only one on this list that has the hero singing The Five Stairsteps to an Intergalactic Villian. To be fair I haven't seen Ant Man yet, but that's tough to beat.
