[thelist] What does this MYSQL command mean?

[CDitty]

I am trying to figure out what one of my programmers is doing here.  Can 
someone explain what this statement is doing?

SELECT id, banner, alt_tag, hiddentag FROM lottobanners where timesclicked 
< numberbought or numberbought = -1 ORDER BY id LIMIT 3,1 LIMIT 0, 100


Thanks
