history of the 500 add

i just realized i have somewhat of a history with tournaments where 500 is added to the prize pool. when i first started playing online poker a few years ago, ub had a week where they added 500 to their nightly $5 tournament.
i was able to play in 3 of the tournaments that week. each had a field of between 800 to just over 1,000 players. the first one i played in i got 2nd out of around 800, the next day i got 1st out of a field of 1,000+, and then the following day, i got 3rd in one with a field of around 900. I cleared just under 3k that week, with $15 invested.. and you'll be f'n gd'd right desert tacos were on berg all 3 nights.
