About T-Shirt Design
Shenanigans Loading T-Shirt works because it sounds more like something a real person would say than a random slogan. Anyone who is into St. Patrick's Day will probably understand the idea right away.
You could wear it for parades, bring it out for parties, or just keep it in the normal shirt rotation. The sarcastic t shirt vibe is there without making the design feel too mean or over the top. It also fits in with funny t shirts for men that are more about a quick joke than a huge graphic. The joke is quick, the message is clear, and that is really all it needs.
