In The Big Bang Theory S04 episode 21, Sheldon Cooper at one point states "I saved a nuns life, why am I being punished?".
Do we ever find out more about this or does the character pop into the series at any point? I am struggling to find anything.

Penny: Sheldon, have you ever kissed a girl?
Sheldon: Other than my mother, my sister and my Meemaw, no. But in the interest of full disclosure, I was once on a bus and had to give mouth-to-mouth resuscitation to an elderly nun who passed out from heat exhaustion. Every year I get a Christmas card from her, signed with far too many X’s and O’s.
