Why does America suck at Clash of Clans?
They already lost two towers.
Alright listen up, buttercup. This joke is saying that the reason 'America' is bad at the game Clash of Clans is because it has 'already lost two towers.' Those two towers are a reference to the Twin Towers that got destroyed on 9/11. I know you're probably picking your nose right now, but try to keep up, sweetie.
