An abundance of alliteration

Alliteration is nothing new (its first known use is circa 1624), and it can turn a nice phrase, like wild and woolly or babbling brook. But lately, there seems to be an abundance of it. Case in point:

Seen on a billboard: Your Posterior Plumbing Experts

Heard on the radio: Snot Specialists and Test drives for Testes.

Well done or going for a cheap laugh?
