You Do What, Where...Why

It’s really quite weird, this thing they call planking,
On a scale of originality, it might earn a high ranking.

The wheels in my boy’s brain have been tirelessly cranking,
In his quest for fun, it seems his mind has been blanking!

Should I question as well whether his intelligence is tanking?
In his high-powered cranium, are there loose marbles clanking?

He may find it unchallenging, on that I am banking,
But quite earnestly, planking really is harmless pranking,
That, frankly, to me, merits not even a spanking.
Heck, Bieber is tweeting about all of his planking.

At least it’s not backflipping, for that I am thanking!

Uh-Huh!

BOOM!
