What invention would you would have liked to take credit for? (for me cup of noodles)?

The internet.      

The Transistor.

This single device opened up the digital electronic age. When you stop to consider how dependent the modern world is on electronics, you realize its the biggest step in progress that humanity has made since the iron age. All made possible by this relatively simple invention.

Side note: I actually did invent the transistor 3 years before the scientists at Bell Labs, but my patent application got lost in the mail. Doh!

The invention of the wheel. More specifically the wooden ones on Horse Carriages from the 1700's. They just look so cool and have so much character.

I would have to say a Condom because it kept me out of trouble many times. 

i dont want to take credit for any of it

Anything /i can get royalties on
