I thought the answer was 42.
You ruined the punchline.
The Sex Studies instructor was teaching class one day, and asked his room full of students how many sex positions they were familiar with.
As the instructor called on each in turn, one student said, “Seven,” another, “14”. A voice in the back yelled out, “41.” The instructor continued calling on students, and got more answers. “Twelve,” “Seven.” Finally, one guy in the second row answered, “One.”
The instructor stopped and asked him, “What position is that?” The student described the Missionary Position.
The voice in the back yelled out, “42!”
