Felicity's humor, part 2

For those of you who enjoyed Felicity's last joke, here's one she told us last night:

Felicity: Where are hat's mouths?
Me: I don't know, where are hat's mouths?
Felicity: On their stripes! (gales of laughter, then thoughtfully)Unless they don't have stripes...

I think my favorite part was the after thought.
