Alright, listen up, genius. The joke is that the person is saying something is going to "boom" like the Twin Towers. "Boom" is used because the Twin Towers exploded on 9/11 during a terrorist attack. So, yeah, it's a dark joke about a tragedy. You probably didn't get it because you're too busy picking your nose or something.
