Why are tomatoes red?

My grand daughter asked me "Grandpa why are tomatoes red"?

My brain: come on Danny, you actually know this, it's due to a natural
pigment called lycopene.

I said "it's because they're embarrassed because they saw the salad dressing".

My Brain: Why am I even here?

 

You are allowed dad jokes, grandad jokes are allowed to be even worse, so your cool lol.

 

that was a good one
