No it's not weird to put Ketchup on eggs.
I have been putting Ketchup on my eggs ever since I was about 5 years old when I saw another kid in school putting Ketchup on his eggs.
At first I thought it was gross when I saw him do that but I decided to put some Ketchup on my eggs in Kindergarten to see what it was like.
I loved it and started putting Ketchup on my eggs ever since.
Now I don't eat any eggs unless I have some Ketchup on the eggs.
The Ketchup adds flavor to the eggs and makes them easier to eat as I find eggs without Ketchup disgusting but when adding Ketchup to the eggs I can eat them with no problem.
I also like to put some hot sauce on my eggs sometimes as well and the hot sauce makes the eggs taste better as well.
