My living will and healthcare directive contains the following wording:

If I am unable to differentiate between, and choose by what ever means of communication are available to me, NFL Football over Men's Ice Skating, (with the exception of NFL Hockey) on television, its time to pull the plug....on me not the TV!!

Of course it's in upper case, having been written before I "met" Leah Ann
