Penetrated Their Mature Facade

(We’re in a basic marketing tutorial, where we’re learning different marketing techniques. Our tutor is a young, trendy PhD student.)

Tutor: “…and the final technique is penetration.”

(As mature university students, we make an effort to hold our tongue and let him continue.)

Tutor: “…We all spend a lot of time thinking about penetration, but unfortunately it’s not the kind discussed here. This isn’t Sexology 251.”

(We all burst into the laughter we’d been holding back. Believe it or not, “sexology” is actually a real subject at my university, and apparently one of the most popular electives.)
