Bolo, the Human, Neutral, Male Barbarian ascended to demi-godhood at 1:04 AM, May 26th, 2005. He had 613 of 613 hit points (woo, perfect health!), an armor class of -42, and just over 8.5 million points when he at last sacrificed the Amulet of Yendor to Crom. Sadly, none of his (many) pets survived. :(
That brings the number of classes I've managed to ascend to 3. Yee-haw!
