Why Funny Birthday Wishes Work Best for Nephews

Nephews hold a special place in our hearts. They’re not our kids, so we can spoil them and send them home. They’re not our siblings, so we don’t have all that childhood baggage. They’re the perfect people to joke around with, tease mercilessly, and shower with inappropriate humor (age-appropriate inappropriate, of course).

A funny birthday wish shows your nephew that you get him, that you’re not just another boring adult, and that you put actual thought into his special day instead of just signing a card someone else picked out.
