This is my brother Ptolemy and this is my other brother Ptolemy

Remember the Newhart TV series with the characters of Larry, Darryl and Darryl? Larry would always do the introductions (since the two Darryls never spoke): "Hi, I'm Larry, this is my brother Darryl, and this is my other brother Darryl."

I bring this up because today is the date, according to the Encylopaedia Britannica web site, that

The legendary Cleopatra VII Thea Philopator, aided by her Roman lover Julius Caesar, was reinstated as coruler of Egypt (with her brother Ptolemy XIV) this day in 47 BC following a civil war with her brother Ptolemy XIII.

I wonder if Bob Newhart got the idea from history?
