Since our currency and economy is so debased as to make it a bad joke and the country is in such a bad state as to be farcical, a woman comedian would be a propos. Jane (you ignorant slut) Curtin, Gilda (Roseanne Roseannadanna) Radner or Lily (One Ringy Dingy) Tomlin. Phylliss Diller would be a good choice; but not Roseann Barr (wouldn’t fit on a $20 bill).
For more serious comedians, Carol Burnett or Mary Tyler Moore.
Another comedienne for our funny money. The late Joan Rivers (R).
