I stumbled across a nifty, yet witty quiz a while back, and still never seriously commented on it.
It basically comprises of “brain-teaser” like questions and they really challenge you to think outside the box. Some may find the answers kind of stupid, while others will probably literally LOL.
The highest question I ever reached was 65. The files may initially take a minute or two to load the first time, as it’s one big flash drive, but it’s well worth the wait, IMO.
