This "Shenanigans..." t-shirt is for the Irishmen because only them understand what this word means. Speaking of the Irish, shenanigans doesn't mean tricky and mischievous. It's the name of a famous Irish Pub. On the annual national day, the irish people are usually up to this place, chugging and drinking green beer or a special wine of the Irish. That's why life is more fun when you're up to something.
