Support til it hurts

I heard a story on the news yesterday about Emotional Support Animals - and apparently it's really easy to buy a letter of authentication/certificate proving your dog should get to sit in your lap for free on a plane. (I am SO doing this, btw.) Got me thinking, though - could I use the certificate to allow me to bring Charlie to work with me, too? I mean, I need her, guys. For emotional support and stuff. #doubtful
