What qualifies as a joke

Sahil: Baba, tell me a joke

Me: (Couldn't think of much) I went to Kaustubh's home and met Shoumik.

Sahil: Baba, that's not a joke. A joke is more like 'I went to Kaustubh's home and ate Shoumik'.

Bigger and stronger

Once I was explaining to Sahil that he is going grow up to be bigger and stronger than me. When he heard that, his eyes widened in amazement and he asked...

"And then, you will call me Dad, right?"
