Did you ever send your kids to school with a handwritten note in their lunchbox? Perhaps something simple like ‘enjoy your day’ or an important reminder like ‘don’t forget soccer practice tonight!’ Well, this Utah father has taken the simple lunch note one step further with these hilarious messages.

Father of five, Billey Ivey, has been penning funny lunch notes for his children for years. The kids, aged 7, 8, 10, 12 and 15, have laughed (and no doubt cringed) about their dad’s jokes in the schoolyard, but now Ivey is getting international credit for his punchlines.

The Utah dad started posting photos of his “napkinisms” on his personal Instagram account. What started out as a family joke has now gone viral, with parents around the world hailing the dad for his hilarious messages.
