I’ve always told my wife that she never has to worry about my fidelity because I’m preternaturaly lazy and dealing with more than one woman is way too much trouble.  To support my case I enter this story from iol into evidence:

Bucharest – A Romanian man lost his wife and mistress in one night
after buying both a personalised gold necklace and mixing up the gifts.

Petru Cioaba, from Focsany, bought identical necklaces for his wife and
his mistress and had their initials and a personal message engraved
onto each one.

But he mixed up the necklaces, and after he left his wife the necklace
one morning as a surprise present for her and went to work, he got a
message from a lawyer saying she was filing for divorce.

And now you know why I’m very glad my wife doesn’t read this thing.
