Years ago, I sawed the arms off my chair in an attempt to free up elbow room. Apparently this weakened the structural integrity of the parts that hold it together since all of the weight is on l-shaped plastic bits instead of complete squares.
The scene where the birds SUDDENLY BEGIN DIVE BOMBING THE TOWN caused me to start thrashing around in my seat, screaming "WHAT? WHAT?! WHAT THE FFFFFFFFFFFFF..." Something went "SNAPPO!" and now my chair is a full-time recliner.
