What's your favuorite quote, or a quote that's just uber great?
Yeah, I was just wondering about people's favourite quotes and sayings and such. I am lately lacking in great stuff just to randomly say and really need some new material. Also jokes would be supercool! And radom words you've created and their meanings, because mibba people are just soooo talented like that. I don't know if this is considered spam (lol, SPAM- it's ham in a can!) and if it is, well, it wasn't intentional. Anything else really random would be cool too, I'd like some cheering up. Long live My Chemical Romance.
