Am i what they say?

My kids popped a surprise birthday celebration on me yesterday.
It was sweet, really sweet, the extent and effort they went into putting everything together.
It was heartwarming when they wrote in my card that i was such a patient, caring, adorable, cute, pretty etc. teacher. (Which i graciously accept and acknowledge. Hahaha. Nah, they've been too kind. They gave me too much credit. I nowhere near any of those. And no, being humble is not my forte too, in case you're wondering.)
But it got me worried when they wrote in my card that I'm "the most entertaining teacher", "most comical teacher" they've had.
I wonder what i did in class that made them say that. I must have been a clown in class without even knowing it. The scary thing is, I don't quite think i'm quite funny at all. Nor do i have a great sense of humour. If i were to describe myself as an ice-cream, i think i'm just a vanilla with maybe some nuts as topping -- the nuts add an occasional zest to the taste of vanilla, otherwise very nondescript. That's all.
Entertaining? Comical? (_ _lll)
