I read this fw email type thing posted in a motocross forum. It gave ideas of little tricks to pull. I did one of them with superb results.
I took DH cell and changed his banner greeting. Most phones offer the option to change the little words at the top of the main screen. We always have ours set to say our son's racing nick name.
Well, I changed DH's banner greeting to "No Service"!!
He actually called the cell company!!! I am LOL as I type this. It worked like a charm. The poor girl on the phone was baffled why her customer (my DH!) who had such a reading on the phone but was able to make calls.
Certainly a great harmless prank to pull. I only wish DH would call the company to fill the girl in!

I love a good joke as much as the next person, but my gosh! That's taking it WAY too far! No wonder he moved out. I'd be ticked too!
