About the Number 95 (ninety-five)

Molly Kool (first North American female to become a sea captain) died at the age of 93. MathBabbler already had a nBAB for 93 so he created a nBAB for 94. While posting the nBAB for 94 he noticed that he didn't have a nBAB for 95.

Barack Obama has said "95 percent" in numerous speeches. For example, in his address to Congress (and the nation) on 24 February 2009, Obama said "95 percent" twice.

   "[...] 95 percent of working households in America 
    will receive a tax cut [...]"

   "In fact, the recovery plan provides a tax cut -- that's right, 
    a tax cut -- for 95 percent of working families."
