I wouldn't say that it's entirely wrong. Here's something from the University of South Florida, St. Petersburg:

Finally, the apostrophe is used in one other way. Although the apostrophe is never used to make a word plural, it is used to make letters and numerals plural: Although I received C's and D's in many of my college classes, I always received A's in my business classes. My sister received straight A's throughout her college career. My score sheet showed that I had six 5's and three 4's.

I respectfully disagree. I think Jesus had really small feet.

He probably confused the idea of adding an apostrophe on for things like 10's, et. al.
