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.

Darren Sykes, 44, set fire to his home in Penistone, South Yorkshire after luring Jack, 12, and brother Paul, nine, there with new a train set.
Sheffield Coroner's Court heard Jack, who later died, told doctors and police his father had set the house on fire.
Both boys were unlawfully killed, coroner Christopher Dorries ruled.
Mr Sykes, who had been divorced for two weeks at the time of the fire, was caught on CCTV buying petrol in portable containers from a filling station near his home in Tennyson Close on the day of the blaze.
He died in the fire on October 22 along with Paul.
Monday's inquest into his death recorded a verdict of suicide.
Before his death, Jack was heard to say "he did it" to doctors and police, the inquest heard.
Claire Sykes, the boys' mum, told the court she still carries guilt for what happened.
She wished she had been home earlier from work, she said, and been able to stop Jack and Paul from going to see their father.
"I wasn't there when they really needed me as a mum," she added outside court.
"The only thing I could do was hold them in my arms when they died."
Andre Spencer, Mr Sykes' former boss, said he was one of a number of people to get a text from his employee just moments before the fire started.
"To be honest, I thought he was being a bit dramatic and that he would be at work the following day," he said.
"It was only when I got a phone call from another person who received the same message that we decided to contact the police.
"He was very depressed. He thought that he was going to lose access to his children."
Barnsley Council said it had begun a serious case review into the deaths.

HMP Birmingham prisoners Demehl Thomas and Moysha Shepherd, both 25, are accused of boasting about drug dealing and violent assaults on rival gang members in the video, police said.
The pair are charged with making a sound recording in jail under the 1952 Prison Act.
They will appear via video link before magistrates in the city on Thursday.
West Midlands Police, which described the video as a "selfie rap", said it believed the prosecution against Thomas, formerly of Vernolds Croft in Highgate, and Shepherd, of Hampstead Road, Handsworth,  was the first of its kind.
Insp Nick Dale, said the law was intended to "minimise the potential" for a camera or recording device to be used inside prison "and possibly compromise security or pose a threat to the safety of prisoners and staff."
Can you name all 32 counties of Ireland?
