Kirby: You are just pissed off and bitter because you have not had sex in... how long? What is it... a year... maybe two? Refresh my memory please, Kevin. Haven't you heard of the sexual revolution?
Kevin: Who won, huh? Nobody. Used to be sex was the only free thing, No longer. Alimony... palimony... it's all financial. Love is an illusion.
Kirby: It's the only illusion that counts, my friend.
Kevin: Says who?
Kirby: Anyone who's been in love.
Kevin: Love sucks.
Kirby: So does your attitude.
