Tell him you have congenital heart disease. That always has them rolling in the aisles.
Seriously, someone from our medical insurance company actually called my husband at work today to let him know that there were counseling services available for my congenital heart condition.

He laughed at her and told her he wasn't falling for it, then called me to let me know that "my little April Fool's joke" hadn't worked, and that whoever my friend was they didn't even sound remotely like someone who worked in an insurance office. Except I did no such thing.
So now I'm wondering if it's just a simple mixup, or if someone at Blue Cross/Blue Shield is bored out of their mind and playing pranks on random people...
