Some grandpas are sweet. Others are GRUMPAS!
Every family has one. The grandfather who complains about everything, tells it like it is, and somehow manages to make everyone laugh!
Introducing the Psycho Jim Grumpa Sweatshirt, designed for grandfathers who’ve earned the right to be a little grumpy.
Featuring the hilarious saying “Grumpa – Like a Regular Grandpa, Only Grumpier!”, this comfortable sweatshirt is perfect for the grandpa who has everything, including an opinion about everything!
Whether he’s relaxing in his favourite chair, enjoying family gatherings, or reminding everyone how things were better in the good old days, this sweatshirt says it all.
At Psycho Jim, we believe getting older doesn’t mean losing your sense of humour.
In fact, it usually means you’ve had more time to perfect your sarcasm!
Psycho Jim – If you’re happy, I’m unhappy!
Order yours today. Grandpa might complain, but he’ll wear it anyway!

Built to Survive Jim
