Bushy basil lessons

I know that you have to snip off the tops of basil in order to make it bush out.  But I only learned last year how early you have to snip off those tops!  Apparently if you snip off the second set of true leaves the plant really starts bushing out.  These are Thai Basil plants - and they are sprouting lots more leaves.  Now I'll have to figure out when to snip off these sprouts to promote more growth and bushiness.

I've done the same snipping on my lettuce leaf basil, emily basil, and genovese basil.  They're a little slower, but they look like they're reacting the same way.
