what is the best gift for firefighter?

Well how long have you been married you could borrow his fire fighter suit and get a sexy picture of yourself to give him or wait to christmas morning and be standing at the tree with it own when he gets up.

Since he is a fire fighter, I think you can give something which is touching and meaningful to him which honors him as a fire fighter. Perhaps you can identify someone that he saved before during one of the emergency and have them write their thankful words and you can order a fireman figure which has your husband's face on it or look similar to your husband. Have him bringing an extinguisher with the testimonial wrapped along it. This should be pretty touching and meaningful.
