Jimmy Kimmel really does have friends everywhere. That or Patrick Stewart just really, really hates people and flying and wanted the world to know it.
Common courtesy is something that people have yet to apply to commercial air travel, which is surprising seeing as it's been around for the last 100 years. It's a bugbear of many, Jimmy Kimmel and Patrick Stewart are apparently amongst said many and as an act of public service displayed the worst traits of the people who ruin flying for the rest of us.
Don't be any of these people. Especially the clapper. If you clap know that everyone hates you.
