Wow, that's gotta be fake. I have three level 60s on my WoW account yet the only reaction I had when I hit 60 for the first time was "Alright! I finally hit level 60!" which I only said in my head.
The first time I hit 60 was with my paladin while grinding on zombies in Western Plaguelands. I later hit 60 with my hunter while doing a Dire Maul run. I then hit level 60 with my rogue while doing quests in Silithus. It took me about 9 months to get all 3 to level 60 (I was playing them all at once along with like 3 other alts, which explains why it took so damn long).
The funny thing about hiting level 60 in this game is that once you're 60, it becomes a COMPLETELY different game. If you don't bother joining a raiding guild, your level 60 will have nothing to do. Battlegrounds takes too long for it to be worthwhile and leveling up professions is boring as hell. You're better off just making another character and getting them to 60 then sticking it out with a level 60 if you don't plan on raiding the 40 man raid dungeons nonstop.
The cake is a lie... THE CAKE IS A LIE!!!!!
