Getting older doesn’t come with instructions. Good thing you stopped following them anyway.

The GuffMark “Don’t Know How to Act My Age” T-shirt features a cigar-smoking gorilla in a fedora, backed by the painfully accurate confession:

“Don’t know how to act my age. I’ve never been this old before.”

With its distressed vintage typography, rugged Americana styling, and unapologetic attitude, this shirt is made for anyone collecting years without surrendering their sense of humor.

Perfect for birthdays, retirement parties, cigar nights, barbecues, or any occasion where acting mature sounds unnecessary.

Age is mandatory. Acting your age is still under review.
