what is a good comeback for: your level of intelligence must be that below of a retard. Don't hurt yourself?

[Kimberly]

this is how it went down, on a social media site. word for word
stranger: Before i got boobs i was an ugly duckling..
me: Boobs don't automatically change your face, retard.
stranger: It's a saying. and wow! Your Intelligence level is obviously below that of a retard to think its okay to use that word so loosely. Don't hurt yourself reading this. lmfao

[Cami]

I've never heard that saying before. Where'd you get it? up your ass? cuz it sure as hell stinks. Just like your fashion sense. xoxox

[Den B7]

So now that you've got boobs I guess you're no longer a duckling, but you're still UGLY!

[reena]

Wow... shallowness at it's best.

Neither boobs nor looks are going to help the two of you get past your ugliness.

[SomeGuy]

Just say Fuck you Reena.

If you're so damned smart, why A) aren't you rich, or B) do you hang out with someone you think is retarded.
