Social media provide a wonderful — but occasionally maddening — forum for passing around silly quips and observations.

This one came across my Facebook feed the other day.

It noted that President Obama’s critics have been fond of referring to him as “Barack Hussein Obama.” Yet one of those critics doesn’t get the same treatment by his foes who could refer to him as “Rafael Eduardo Cruz.”

To be fair, I don’t recall hearing Texas Republican U.S. senator and presidential candidate Ted Cruz use the president’s full, given name when referring to him. Maybe he did. Whatever …

I have heard the president make plenty of fun of his own name.

During two appearances with Republican rivals at the Al Smith Dinner in New York City — which is a political ritual of sorts, bringing opponents together for a night of fun and bipartisan fellowship — Obama cracked jokes about his name.

In 2008, he said he got his name from “someone who never thought I’d run for president.” Referring to a line that Republican nominee U.S. Sen. John McCain had used in a debate with Sen. Obama, he joked, “Barack is actually Swahili for ‘that one.'”

In 2012, while running for re-election, the president noted something in common with his GOP foe, Mitt Romney. “We both have unusual names,” he said, noting that “Mitt” is Romney’s middle name. “I wish I could use my middle name,” the president quipped with feigned wistfulness, again to huge laughter.

What’s the connection between Obama and Cruz? They both have faced — and are facing — equally ridiculous questions about their eligibility to seek the presidency.

What’s the lesson here?

It might rest in that old saying about something being “sauce for the goose … and the gander.”
