My nephew and I have a very similar sense of humor. I've always sent him humorous cards and often cards that are somewhat off color. I made him a funny card for Christmas last year and he laughed his head off.
You might recognize the foil paper from other posts. I backed the picture with gold and covered the card front with the red before adding the backed picture.
I followed the same procedure with the inside and voila! I just love this dog, lol!!!
