When you have a plugged nose it tomes out sounding like Toilet Painter.

Also we got it off of a looney tunes cartoon where the little Duck was putting everything in the toilet. He would say toilet painter go down the hole, telephone go down the hole etc.

that is so cute that you two still have little sayings and personal phrases that are meaningful to you both, and you still laugh about it.  It's one of the cute things that I miss about being married.
