The sensible dip

It's sensible for a mother to dip her finger into the child's milk,
The right temperature range, lest a tweak.
Just like a jogger surveys his route, whether flat or tilt,
To keep performance peak.

ha, makes sense to me.

And now, let's take a look just past the halfway mark of the race... Yes, yes, he's still going. Timothy is still making progress, ladies and gentlemen, no matter how slow. There appears to be a checkpoint around the corner. Yes, it is. And he's taking a rest. It looks like nobody is in front of him! Wa- wait a minute, there's nobody behind him! Why the hell is he running?

WRONG RACE LADIES AND GENTLEMEN!
