Angela (in the car, on the road):  Was there a divider here at some point?  It looks like they added lanes.

Jeremy:  No, I think these were always here, maybe they just changed the lane functions.  Or maybe they smalled them up somehow.

Angela:  Smalled them up, huh?

Jeremy (totally oblivious):  Yeah.

Jeremy starts laughing, right away but obviously about something unconnected.  (Background break:  When Jeremy was about four or five, his mother drove over a tummy-tickling hill and Jeremy cried out, “That whees my bum, Mommy!”  I can’t figure out how to spell “whees”.  But it’s “whee” as in an expression of enjoyment on an amusement ride.)
Angela:  What?

Jeremy:  I was just thinking of the grammatical hilariousness of the phrase, “That whees my bum”.

Angela:  Hilariousness?  …Hilarity?

Jeremy:  Well yeah, but it wouldn’t be so funny if I said it right.

And he continues to drive along, both of us totally cracking up.
