Fiddle Dee Diddle Dee Dee

I wrote this about two years ago, on Facebook. I decided to save it. I'm glad I did. I think it's mildly amusing.
 
Fiddle Dee Diddle Dee Dee
Oh, I remember when sliced bread hit the shops
I said, "This will be something nothing ever tops".
Old, old, I feel so old
Fiddle-dee diddle-dee dee.

Oh I remember the bubonic plague
I was already in my middle age.
Old, old, I feel so old,
Fiddle dee diddle dee dee.

Oh, I remember the building of Stonehenge
I said, "My, my, how architecture has changed."
Old, old, I feel so old
Fiddle dee diddle dee dee.

Oh, I remember the pyramids being built
I said, "They're like the old ziggurats with a tilt".
Old, old, I feel so old
Fiddle dee diddle dee dee.

Oh, I remember the dinosaurs dying off
I said, "I predicted this, and how they did scoff"
Old, old, I feel so old
Fiddle dee diddle dee dee.

Oh, I remember the start of sexual reproduction.
I said, "I'm telling you, this will cause some ructions."
Old, old, I feel so old
Fiddle dee diddle dee dee. 

Oh, I remember that ole Big Bang
I said, "This is exactly how the last one began."
Old, old, I feel so old
Fiddle dee diddle dee dee.
