But I think there's a difference between when you do something like that to intentionally make someone's day brighter and when you do that to just look like a jackass. Hence, Gundark's example of being in Trekkie gear during Jury Duty. There's just no purpose whatsoever in that. What you did is different. That does not make you a geek. It makes you a bit of an entertainer. No harm in that.
