You've been there, sheepishly telling the firefighter brandishing calendars about your workplace that it'll be a gift for your mother, or friend. Then fixing it firmly to your pin board for the next 12 months.
If you couldn't resist a firefighter's calendar before, there's certainly no hope for you now with the latest offering out of Australia.
The country's annual firefighters calendar has featured the nation's sexiest firefighters posing to raise funds for the Children's Hospital Foundation and the Westmead Children's Hospital's burn unit charities since 1993.
This year, with proceeds also going to the RSPCA, they've added puppies to their photos.
The adorable pooches were loaned from Safe Haven Animal Rescue and are all available for adoption.
The firefighters' availability is currently unknown.
