I thought the upside down text was more April fools. As someone earlier said they thought something was wrong with their computer. Oddly enough I didn't notice because my brain doesn't function correctly. My girlfriend was sitting with me when she asked "Why is that upside down". Years of reading drawings over someones drafting table or desk upside down, or someones sketch in the field. Apparently I'm good at reading upside down. Might stick it on my resume lol.
The pony's or whatever they are didn't seem much april fools to me, you knew right away it was something someone did on purpose. Also whatever they were was after my time. I didn't get it all.
