Seagulls caused 911.

Seagulls are one of the many "Spawns Of Satan"s. Look at them,

They have horrifying beaks, their feet just look.. Evil! They have wings; EVIL.

Plus, a flock of seagulls attacked the airplane in 911. This is a proven fact.

According to the "We Don't Know Shit" science lab, seagulls were spotted right after the plane crashed. They were laughing and flapping those evil wings.

Watch out. Seagulls are everywhere.

This is just another reason to hate the beach.
