Ireland is well known for producing some of the greatest actors, singers, and sportspeople over the years.
While some have risen to the heights of fame that are unfathomable to the average Joe, there is one thing they have in common with the general public - they too had to traipse to school back in the day.
Just like every youngster, they would have been weighed down by schoolbags, oversized uniforms, and the general malaise of being a teenager.
