To forgive is Mulligan

For some reason, the saying, "to err is human" popped into my head, only I couldn't remember how the second part went. So, google is my friend.

To err is human:
-to forgive divine
-to arr is pirate
-to 'screw up' is part of the languange
-to give up isn't a bad idea
-to report it is another matter
-to Eruv is Jewish
-to blame someone else shows good management skills
-to forgive just takes a good PR campaign and a spot on CNN
-to Moo, Bovine

There were tons of different ones, I think the first one is the original one though, wouldn't you say?
