It's not as easy as you think, but then try pairing them all with a character from The Simpsons.
That's just what Brian Quinn from Londonderry has done for the Irish Simpsons Fans Facebook group.
Like all great ideas, Mr Quinn said it started out small and then kind of escalated.
"I probably had one pun in my head - I think it might have been DoneGil first," he told BBC News NI.
"I started scribbling more down and I think I had about 17 and I thought: 'I might as well do all 32 now.'
"My girlfriend was watching Grey's Anatomy or something, so I just got out the laptop and started messing about."
By Thursday evening, his post was closing in on 1,000 likes.
He said he was surprised at which ones seemed to be the most popular.
"It's funny, the last couple that I thought of probably got the most likes and I thought they were kind of scraping the barrel," said Mr Quinn.
"They were the Cork one - Hank Skorkio - and the ones for Meath and Westmeath."
Ireland Simpsons Fans started on Facebook in January 2016 and was the brainchild of Jack Leahy from Dublin and Paul Loughran from Belfast.
Mr Quinn is now the page moderator for the site.
As for his own personal favourite, a bit of hometown favouritism might be at play.
"I'm from Derry and I actually think the Derry and Kerry - Sherri and Terri ones are the funniest and the cleverest," he said.
Can you name all 32 counties of Ireland?
