A girl and her boyfriend decide that they are finally ready to take their relationship to the next level: sex.
The boyfriend is all excited and he goes to the pharmacy to get some condoms. He walks up to the pharmacist, and being nervous, keeps his voice down: "I need a condom." The pharmacist asks "What kind?" The boyfriend is quite nervous at this point, and explains that he and his girlfriend are about to get started, etc etc, they are moving into a new area in their relationship. So the pharmacist explains what the differences are, lubrication, etc. By the end, the boyfriend has a bag full of stuff.
As he is walking to his car, he gets a phone call from his girlfriend: "My parents just invited you to dinner tonight. Dinner is at 7."
Fast foward to the dinner table...They all bow their heads before dinner to say Grace. 30 seconds or so go by and they all raise their heads, except the boyfriend. 1 minute goes by...2 minutes...at the 5 minute mark the girlfriend leans over to her boyfriend to say "I had no idea you were so religious!"
The boyfriend leans over to reply "I had no idea that your father was a pharmacist!"
