Sorry. I couldn't resist.
Did I mention that in this case, the "G" rating stands for "groaner"?
edit: I'm not sure whether the punch line will make any sense to those outside of the United States. If it doesn't, you are missing a piece of the puzzle: The Indianapolis 500 (often abbreviated as the "Indy 500") is a car race famous throughout the US. I don't know how well-known it is in other countries. (I am not at all into racing; I don't even know whether it is a national or an international event.)
As always, all comments welcomed.
Joy,
Lynn
