I would not wear a trimmed mustache. Because they're bristly.
Every now and then I look in the mirror and think, "Gosh, I have a big mustache. ... It looks kind of odd, doesn't it?"
A man with a mustache doesn't get chapped lips.
I figure I've got it now so ... that's me now. But I'm not trying to impress nobody.
I think [size] does matter ... guys are kind of jealous of the guy that has the really long handlebars.
There was a time when I kept it waxed and twisted out. I guess ... my vanity faded enough that I didn't think it was worth all the effort, so I just kind of let it run wild.
I was cowboying out of Laramie, Wyoming. Everybody had one, so I grew one too.
I've had it so long now that I think if I shaved it, I wouldn't know myself.
I think now mine's pretty conservative and boring compared to what it used to be. It's all in your perception. 
It just hides a part of your ugly face! That's the most practical advantage I can think.
I shaved it off once for a girl I fell in love with that didn't like mustaches ... She said "there's something missing." ... I'll never shave it off for a woman again.
There's this misconception that it takes a lot to grow a mustache ... It's not like there's some miracle additive, you just stop cutting the damn thing!
I think a man's outward appearance projects a lot of his character to someone.
It's an attachment to the past. ... I think the more we can hold onto—modify it as necessary...—but the more we can hold onto, the better.
