Who had the mumps

A symptom of the mumps is a sour taste in the mouth.I backed Maldini today ridden by Davy Russell and just after the race I got a sour taste in my mouth,i don't know if I am getting the mumps or was the taste caused by davy's bad ride on the horse.

Anyone who cares to watch the replay of the race be careful because you may catch the symptom I am talking about.
