Repetition, repetition, repetition

It's a good trick in headline writing. Especially when you use a word 3 times. I was reminded of this when I saw an old deep pan pizza slogan:

Real Deep. Real Good. Real Thing.

And then again when I remembered the old Martini slogan:

Anytime, anyplace, anywhere

(I used to have a belt with that written on – it was yellow plastic with red and blue writing. Mmm, nice!)

Perhaps this could be called the rule of 3 + 1. Repeat something 3 times, and add a touch of innuendo.

It sticks in the memory.
