This is probably the oldest one around that seems to come and go every so often.
Right now in the General Assistance (How Do I?) forum the thread titled Gizmo's UBB.Threads 7.x Transfer Guide for Dummies (or not) shows up in the index as two pages long... when in fact there is already a third page.
So you click on the [2] only to find once the thread loads up that you have to click on page [3] which actually exists to read the newest post.
