learning experience in class or in university

I really had,or may i say, always a humorous experiences in the class and as well in the university itself. A couple of days before weekend, while having our class in Chem 19 our professor ask us about a kind of food sprinkled with sesame seeds( which is the "Binangkal" she's referring to) as an imaginary example of J.J Thompson's model for atom. Suddenly, my classmate energetically answered " Mam, Atis!" All of us sarcastically laughed at her about such idea. Where can we find in this world an atis sprinkled with sesame seeds? what a silly answer.....hehehehehe...........^^,
