Do bananas come from pineapples?
Discussion
The difference between many things comes down to chemistry. The answer to that particular question can be found in the upper right image. 
BAHAHAHAHA
Yes.
For the record, I was asked this once in a serious tone.
I just said no.
The concept of what one defines as a serious question appears to be changing. I think your approach is probably more rational than mine. I have found that when someone does ask something stupid, turning to look at their ear in profile and saying "blow me, I can see daylight" has negative consequences.
My apologies sir. Upon reflection, I realised I had responded to the stupid question with a flippant answer without questioning my assumptions.
I therefore ventured out into the Costa Rican wilderness to challenge my assumptions in an endeavour to verify the origins of bananas. Whilst I can confirm they appear to grow on plants (picture 1), I asked a local resident (picture 2) whether the plant root base was actually a pineapple. He did not appear to speak English although I got the impression he might have been answering the wrong question as it sounded like “keep nostr weird” 
Love this. You're great!
