Stupid wording IQ question

A couple years ago, while I was still unemployed, I was so bored that I made up jokes and IQ question. One of my favourite one was:

Q: 一 paul 樹, 邊部分最hea?
A: 葉, because 葉德嫺.

But christina and all of my friend keep saying this sucks and this is stupid and blah blah blah.

Lately, I was watching TVB's 係咪小兒科, one of the IQ question is actually very similar and it seems like those kids really enjoy it.

Q: 正方形和圓形去賽跑, who will win for sure?
A: 正方形, because 鉛筆跑.
What the heck, this is exactly my idea.

and one more from my friend karen
Q: what plant knows how to skate?
A: 花, because花識溜冰

another one
Q: All the fruits went to picnic, when they are done, the teacher was counting names, and suddenly one fruit is missing, which one?
A: 榴槤忘返


Q: What kind of 遊戲 we should always avoid playing?
A: 石, because 石油汽
