America's Jenga Skills

Listen up, buttercup. This joke is dark because it makes fun of the 9/11 terrorist attacks on the Twin Towers. Jenga is a game where you remove blocks from a tower until it falls. The joke implies America is bad at Jenga because they already had two towers fall (get it?). You are not smart because you think America is a country, which is very cringe, it is a continent.
