1. Inspecting the gunk from your blackhead strip.
2. Or better, squeezing a blackhead and watching it pop out in a long and lovely trail.
3. Pulling out an ingrown hair.
4. Picking out a really hard and crusty bogey that's been stuck in your nose.
5. Or blowing your nose into a tissue and then inspecting the contents closely.
6. Cleaning out the earwax from your ears and being happy about all of the dirt on the cotton bud.
Better than sex, guys.
