What are some good comebacks for an insult?

It gets on peoples nerves when you sound confused and polite.

person: You'r a gay freak!( there is nothing wrong with being gay i am just saying that if they call you gay and you are not just say this)

You: Really now you learn somthing new everyday!

person:4 eyes!

You: No i only have two eyes these are my glasses and talking of glasses if you think that these are eyes then you may need them.

person: You'r moms so fat!

You: Well if so then our moms have one thing in common so far.

Try those then!!!

Oh and also if someone calls you gay and you are just say..

Yes actually i am gay you got that right well done.

and walk of.
