In
Victorian England, turkeys were popular for Christmas dinners. Some of the birds
were raised in Norfolk, and taken to market in London. To get them to London,
the turkeys were supplied with boots made of sacking or leather. The turkeys

the road. Boots were not used for geese: instead, their feet were protected
with a covering of tar.

Here's what Velcro looks like close up:

The Great Pyramid was built circa 2560 BC
Cleopatra lived 69 BC-30 BC and the first Moon landing was in 1969, AD
Cleopatra lived 69 BC-30 BC and the first Moon landing was in 1969, AD
which means Cleopatra lived closer to the Moon landing than she did to the building of the Great Pyramid. Speaking of the pyramids,
they were as old to the Romans as the Romans are to us.
and in 1969, man landed on the Moon.
PHEW! That was
intense.
