Sam on wishes

Sam does not like it when I wish on birthday candles, or eyelashes, or coins in fountains, because I won't tell him the thing for which I wished.  Everyone knows that if you tell, the wish won't come true.  However, some years ago Sam came up with what he thinks is a really foolproof system for how to make it okay for a person to tell their wish:

I find this to be somewhat flawed in terms of logic, and do not do this, which really burns his biscuits. 

He also does not use his own system.
