gene says, " i was quite a card tonight myself." explain what he means and provide evidence to support that he was a card. he is cracking himself up.

Gene ,makes a sarcastic remark commenting on what his teacher always says,

I listened so hard that I nearly differentiated it from the others, and it seemed to be saying, “Finny, give that bone the old college try.”

I was quite a card tonight myself.

Gene's joke was mixed with sarcasm and dark humour.
