X: How come you never tell me you love me?
B: *wtf look* I always tell you I love you!
X: No you don't!
B: ... I love you baby.
X: That's not the right way.
B: Well then, what's the right way?
X: If you loved me, you'd know.  *cracks up*  I couldn't keep a straight face.
B: Tell you what.  I'll write love on my left hand, and then punch you in the face [with my right hand].
X: That makes no sense!
B: Yes!  Just like love makes no sense!
