In re-watching the whole series recently, I've been quick to notice the mind-boggling number of times Picard and Riker in particular are constantly yanking at their shirts when standing up. Sometimes they seem to yank at them without even getting up first. It's like their hands have this serious obsession with their shirts and pulling them. I wouldn't be surprised if they eventually tore a hole in the poor uniforms.
Surely everyone has noticed this. I mean, I certainly understand why people do it on a basic level. The shirt gets ruffled and all that. But the way it's done, I swear it's a psychological addiction or something.
If you haven't noticed, I challenge you to watch several episodes and start counting the number of times this is done. It's hilarious.
And a tad odd at that.
