When I was 14 in high school health class, we were told there was a difference between "semen" and "sperm." Wearing a condom stopped the "sperm" but not the "semen," which was where HIV lived. Then the teacher brought out chicken wire, baseballs, and a fire extinguisher to drive the point home.
Yeah, evangelical times were crazy back then where I grew up.
Can confirm. We have 2 Dodge Ram 550s for our ambulances. And the photo clearly has F-550 on the sides.
