Papa Knows Everything T‑Shirt | Funny Dad or Grandpa Gift
Price range: $19.97 through $25.97
Every family has that one guy who holds all the answers to the universe. Whether it is fixing a carburetor, giving unsolicited driving directions, or explaining obscure history, Papa always has a response ready. And if he actually doesn’t know the answer? His imagination is way faster than a Google search.
Every family has that one guy who holds all the answers to the universe. Whether it is fixing a carburetor, giving unsolicited driving directions, or explaining obscure history, Papa always has a response ready. And if he actually doesn’t know the answer? His imagination is way faster than a Google search.
This Papa Knows Everything T-Shirt perfectly captures the hilarious reality of grandpa wisdom. The design features a bold, masculine layout with heavily distressed vintage typography that reads: “PAPA KNOWS EVERYTHING. IF HE DOESN’T KNOW, HE MAKES STUFF UP REALLY FAST”.
It is the perfect sarcastic gift to poke a little fun at the family storyteller who absolutely refuses to say “I don’t know.” Printed on premium cotton, it is comfortable enough for his afternoon naps and durable enough for his garage projects. Let him wear his “expertise” with pride.

Washing inside-out is the most important step!

Turn inside-out. Use a gentle cycle with mild detergent. - No Bleach
Avoid bleach and fabric softeners, as they can break down the ink. - Tumble Dry Low
Low heat is best. Hang-dry works even better for longevity. - Do Not Iron Print
Cool iron inside-out if needed. Never iron directly on the design.
