There was this time when my dad went fishing. He was so excited when he got a big bite. But when he reeled it in, it was just an old boot. He was so disappointed at first but then he started to joke about it, saying he caught the rarest 'boot - fish' in the lake.
Sure. Once my dad tried to cook pancakes. He mixed up the salt and the sugar, and the pancakes came out really salty. We all had a good laugh when he took a big bite and made a funny face.
It could be that the situation around his death had some ironic elements. Like he was always so careful about one thing, say not getting wet in the rain, but on his last day, he ended up in a big puddle and it just makes for a strange and funny story to tell later. It's not making light of his death, but finding the odd and humorous moments in the events leading up to it.
When I was a kid, my dad tried to build a treehouse. He had all these grand plans. But in the end, the treehouse was so wobbly that it looked like it would fall apart any second. We all laughed about it and he said it was 'artistically unsteady'.
When I was at a school fair and about to ride a rickety old roller coaster, my dad inspected it thoroughly. He pointed out every little loose bolt and told the operator it wasn't safe for his 'precious child'. The operator was a bit annoyed but fixed the issues. Dad stood there the whole time to make sure I had a safe ride. It was both funny and heartwarming to see him be so protective.
One funny dad birth story is about a dad who was so nervous during the delivery that he fainted right when the baby was about to be born. When he woke up, he saw his wife holding the baby and he was so embarrassed. Another one is a dad who accidentally locked himself out of the delivery room while running to get ice chips for his wife. He had to bang on the door until a nurse let him back in. And there was a dad who thought the baby would come out clean as a whistle, but when he first held the newborn, the baby pooped all over his new shirt.
Once, a new dad was trying to change his baby's diaper for the first time. He got the diaper on backwards and the baby just looked at him with this confused expression. It was hilarious.
One example could be that your dad was always misplacing his keys. On the day he passed, the family was looking everywhere for the keys to his car because he had some specific instructions about it in his will. After hours of searching, they found the keys in the most obvious place - in his hand. It's a bittersweet, funny moment.
Here's one. A dad says, 'I'm reading a book on anti - gravity. It's impossible to put down!' Another is, 'Why don't scientists trust atoms? Because they make up everything.'
