Acme Anvils hit my kids every couple of days....

I always giggle to myself when I see the boys hit the wall.  You know, after going full speed swimming, biking or playing, just the simple request or phrase of anything turns into a full blown wail storm of crocodile tears...

It kinda reminds me of old Bugs Bunny cartoons when Wile E. Coyote is chasing the Road Runner; kids are going along full speed them BAM! Down for the count.

Actually, I think Wile E. Coyote is the quintessential preschooler.  Just going and going, thinking it is a good idea, chasing after the fun.  To be ultimately smashed by the acme exhaustion anvil.
