On my flight to Portland, an 18 year old kid behind me was saying the darndest things (sounded like he had just enlisted in the air force):

• that building looks like a Lego I built once
• it was inspired by my lego
• or maybe my Lego was inspired by that building
• the propellers sound like they are cutting through something
• ...like the fuselage
• ...like it was made of red meat
• beef - it's what's for dinner
• pork - the other white meat
• whoa that plane in front of us almost hit that X
• you can crash into something and still fly... we're crashing into a cloud right now
• looks like we're gonna land in water
• the pilot screwed up the landing ... but we can still careen off the runway
• landing in 3... 2... 1.... 321... .... ... there 

I found the commentary amusing, but what if you had flight anxiety? ;)
