Not smart enough

I agree... jokes and rhetorical statements do offer the best opportunities for an exchange... but I'm not always smart or clever enough to come up with a retort! For example... what the heck do I say to "Bez-tiality"!?!? That one was so good I was stumped! Laughed my booty off, but couldn't think of a thing to say other that "oh yea?!?.... your mama!"

I hope to get smarter in the future so I can reply quickly to everything!
