Evil sorcery

[Billy]

S. you will laugh good.  I went right up behind my wife and clamped a hand hard up to her ass cheek.  She could have (would have normally) exploded.  Timid as can be she told me, "stop that." 

I walked in front of a table she was standing at to be in front of her and asked firmly, "Who's yer' daddy now?"    Hilarious S.  Did I get it? HA HA

But, more seriously, what cue to remind heart to apply as a way of doing persistently?
