Mark went to St Patrick's National School, which was outside of sligo, he also went to Summerhill College, where he met Shane and Kian, and they form IOU. He has a birthmark on his back which he refers to as a 'splodge'. Strangely, his brother Colin's got one as well! Mark had a part in a Cub Scouts play - and he had to dress as a woman, complete with clip-on earrings and a dash of eye shadow! He always keeps his toothbrush in a glass by the sink - and he goes mad if anyone moves it! He once had a job in a restaurant - he was paid £2.60 an hour - and used to have to clean the toilets as part of his job.
Mark's dream house is Big house with swimming pool + tennis court in Sligo. Mark would also really like an apartment in New York! Mark says he would pose naked, but only if he was paid a million pounds!
