フランスピアノ「小学校の先生」France Piano · Elementary School Teacher
In a skit about an elementary school teacher, one performer keeps failing to act like a teacher and gets stopped.
The words appear when the audience laughs.
やっぱり教育って奥深いですね
Education really is profound after all, huh.
Textbookやはり教育というものは奥が深いですね。"やっぱり" is the everyday form of "やはり" (extra "っ" for emphasis); "って" casually replaces "というものは", and "奥深い" is "奥が深い" without "が".
