Very naughty, Neil Patrick Harris!
The 42-year-old How I Met Your Mother alum posted on his Instagram page Saturday a special photo celebrating a major social media milestone.
"Since I've reached 3 million followers on Instagram, I thought I should finally post a dick pic," he said, alongside the photo, a publicity image of Dick Van Dyke from the '60s.
"Yes, it's [a] jolly holiday," one user said.
The Mary Poppins and Dick Van Dyke Show actor, who recently celebrated his 90th birthday, has not commented.
More than 30,000 people liked Harris' post.
The actor usually posts family friendly pics on his Instagram, namely photos of his and David Burtka's adorable 5-year-old twins, son Gideon Scott and daughter Harper Grace.
Earlier this week, Harris shared a sweet family pic showing the four making Valentine's Day gifts and cards ahead of Sunday's holiday.
