The Myler debate was over which of the two he scored a hat trick against when it turned out the answer was both.
The Limerick one was before my time but the Harps hat-trick came in the Premier Divison at home in a 4-0. Mick O'Byrne scored the opener before going off injured and was never the same player again. Myler scored 2 penalties and an audacious lob from halfway, the day after David Beckham did the same thing against Wimbledon.
I've been told in the past that one of the Limerick goals was similar but only have vague anecdotal memory to support that and could easily be confused. I'm sure CTID can clear up the matter.
