In seriouness, having the Leaf team do it would be idiocy.
But having a bunch of fans in blue and white jerseys would be hilarious and great fan participation. I'd be even down for that.
Doing that flashmob outside of ACC would great. Everyone walking around normally and then the bass drops and they're suddenly all decked in Leaf jerseys.
That would work.
I have no problem with the fad, just as long as it passes by just like all the others have. The first couple of times are funny, just for the pure randomness, then it becomes the same thing time after time.
edit: And I would not have known about it at all if it wasn't for Ray William Johnson keeping me in the loop on the sometimes hilarious, sometimes stupid youtube "scene"
Lol now this is what the Leafs should do, remake this video with all the new guys. Tell me seeing Kessel singing Leafs are the best wouldn't be the most hillarious/awkward things ever. Btw, whats with all the overcoats and mustaches back then?
