A: Why are you so excited?

B: Look, I’ve found this honest-to-goodness map. I almost can’t believe it!

Note: This phrase means “real and genuine.” Literally, it means honest to God, to whom a devout Christian will never lie. When Christians want to emphasize that they’re telling the truth, they swear and say, “honest to God, I’m telling the truth.” Over time, people have often replaced this saying with honest to goodness, for obvious reasons. “Goodness” here is a substitution of the word “God,” so as to avoid potential blasphemy.
