One time just before Christmas a couple of years ago, my T inadvertently left an opening for comments from everyone. Being impulsive, well... that was way too tempting. Couldn't let that opportunity pass me by. So, since it was close to Christmas, I thought he might like a remake of a favorite Christmas song, and I posted this:

Jolly old dear therapist, lean your ear this way.
Don't be hatin', it's not nice; I just want to play.
My next session's coming soon, now you dear old man.
Don't suspend me; I'll be good, with a new behavior plan.

He closed that loophole very quickly.
