I'm sure most, if not all, of these have already been mentioned but here's a few off the top of my head...
Manners
Common decency
Common sense
Accountability
Chivalry
Respect for elders
Battle of the Network Stars
Proper use of lanes on the interstate
Journalistic integrity
Shopping cart corral etiquette
The ability to laugh at oneself
Politicians looking out for the best interest of their constituents over and above their own self interest
The ability to distinguish between comedy and being politically incorrect
And just in the last two years...respect for the office of POTUS
