Combo threads on 4chan and other message boards have a history of annoying anyone that sees them through to completion, but nothing takes the cake more than a good old fashioned 3-image Slowpoke, taunting all the would-be combo breakers as he waddles into existence.

With his dopey face and flagrant disregard for hastiness, it's the ultimate insult to posters who like to think they're good at keeping on their toes.
