Hehe, also a joke of sorts that you may have heard before...
Mama tomato, Papa tomato and baby tomato are walking down the street, headed somewhere important.
Baby tomato starts falling behind.
Daddy tomato turns and says c'mon son let's go.
Baby tomato catches up, but soon lags again.
Daddy tomato turns again and says 'second warning'.
Baby tomato catches up, but soon lags gain.
Daddy tomato turns and walks to him, squashes him and says 'catch-up'.
Thanks to Cinjin for making it more 'sig space' friendly.
