73 is an Arc Number in Chrome's Show of Chromeyness. It's importance is not explained yet, but it has something to do with the strange remote that Chrome protects.
- 73 is the 21st prime number, and 21 occasionally appears in the show.
- Chrome's number of production is mentioned once as being 73520, as in the 73520th experiment Paradox Science has worked on since 1900.
- Nobody knows the true meaning of 73, but the creator apparently knows "all about it".
- The arc number's purpose will never be revealed according to the creator, as the origin of the number is actually relevant to the creator's life.
- 7 + 3 = 10
- 10 - 7 = 3
- HALF-LIFE 3 CONFIRMED.
