[Ad- gifted product] Daddilife Books, a group of bloggers and writers who happen to be dads, have released another book! Much like their A Joke a Day book, this book also is all about jokes; A Knock Knock Joke a Day, contains a knock knock joke specifically to tell, each and every day of the year (including leap years), that are dad approved and will get our family to at the very least groan at you. Knock Knock Jokes are a whole joke type on their own – one that everyone knowns. This book of jokes are all family friendly, and having one a day starts your day off right.
