Kyle Mooney and Aidy Bryan collaborated with Saturday Night Live host Amy Schumer last night on a pretty tired spoof of a standard-issue porno scenario, the hotted-up teacher who keeps the delinquent student after class to teach him a “lesson.” You know, a lesson — get it? In this case, the not-so-seductive seduction was repeatedly interrupted by Bryant’s earnest student, who kept returning for advice on the upcoming quiz-test-oral something-or-other.

Like Bryant’s dim babe, however, the bit overstayed its welcome by several minutes.
