Jackson fell asleep on my lap new year's eve while we were watching the first three episodes of season one of Saturday Night Live. He was awake long enough to see Andy Kaufman lip-synching the Mighty Mouse song ("Here I come to save the day!"), which he made us rewind twice, but he conked out before the amazing and neverending Simon and Garfunkel reunion (they cut all the sketches to make room for the music, can you imagine that happening now?).
