The idea underlying the well-known limerick
There was a small girl indiscreet /
Who asked her mom for a sweet. /
Mom said, “Aye, it’s here in my pocket!” /
“Go stick your lil thumb in a socket!”
is essentially ill-conceived. For one thing, one finger is not enough to produce the desired effect.
For another, all household sockets are designed so as to preclude any finger abuse, a child or not a child.
