The 41-year-old lad is the 40-year-old Lad in future form. He is a leprechaun, so that means that the 40-year-old Lad is a leprechaun! Unlike the 40-yr-old Lad, the 41-yr-old version doesn't have a pink umbrella...he enjoys throwing jars of jam at people who don't do a jolly Irish jig whilst smoking a pipe, so, both the 40-yr-old AND 41-yr-old version are cruelly disgusting LEPRECHAUNS!!!!!
He built a worm-like time machine called the Time-Travelling Tapeworm 2000 and travelling to the present. The End lalalalala XOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXOXO! Wait a mo, why is this part of the XOXOs blue?
