I'm kinda bad at shopping for men... idk its just hard... but here are some good ideas. Books are always good! If your dad likes history, maybe get him the book that inspired the musical Hamilton! I think that would be a good one. There are also lots of funny-man biographies out. I think Martin Short has one, Patton Oswalt has a book about movies thats good if your dad likes movies, Nick Offerman has a book called "Paddle Your Own Canoe" that seems to be THE father's day book to get. If your dad likes dogs and fiction maybe something like The Art of Racing In The Rain. And Cookbooks are always an option! Is your dad a Home-Improvement buff like mine? Home Depot Gift Card! Lol might not be the most fun thing ever, but my dad really likes it. Got a lot of money? Lol. That sounds rude... but its true. Treat your dad to tickets to see Hamilton! That seems to be a musical that dads can get on board with. Lol. Or get him the soundtrack if you can't justify the ins...
