How many celebrity tournaments have they had?Just curious.

And,in the past 2 seasons of the daytime version of "Are You Smarter Than a Fifth Grader?",in addition to the question I asked about how many celebrity tournaments the daytime version has had,here's another question.In the past two seasons,have they ever,on the daytime version,had players who have gone for the fifth-grade bonus question worth $250,000 and answered the question correctly and won the grand prize?
