A Good Pun is its Own Reword

A photon checked into a hotel, a rather interesting sight. It was asked "Do you have luggage?" It said, "No, I'm travelling light." When I'm at home I like to read books, and relax in my dressing gown. I'm reading a book about anti-gravity. I just can't put it down. Staying in shape is important, of that there is no doubt. I keep trying to exercise but it just isn't working out. My friend fell into an upholstery machine - one of the strangest things I've ever seen. Everyone was shocked and exclaimed "Wow!", but I can say he's fully recovered now. Mathematicians are so smart. Their work is often stunning. But to the guy who invented zero, thanks for absolutely nothing! There was a WWI soldier whose name was Bobby Pederson. He survived both mustard gas and pepper spray. He was a seasoned veteran. Computer scientists are brilliant, I must admit. How much do they like 0 and 1? Quite a bit.
