There's never a good time to tell the little ones about the birds and the bees, so how about an illustration instead? These Men's Blue Humping Reindeer pants will have your family doing a double take as you strut your way down to the dinner table. Catch them off guard with this innocent-looking Fair Isle blue pattern, complete with snowflakes, sparklesâ¦and a pair of reindeer getting it on. Santa didn't get all those reindeer by writing to the stork, so embrace nature and throw on these Christmas joggers this holiday season. They're as comfortable as they are offensive, so keep warm while the snow falls. Pro-tip: don't wear these when Grandma's around.
