16 across: Comedian suffered friendly jeers (5,8)
This anagram should go down in the unwritten annals of cryptic crossword genius (although I still consider Tony Blair MP as an anagram of I’m Tory Plan B to be the height of genius). Here, we’ve got friendly jeers as an anagram of Jerry Seinfeld, so that suffered friendly jeers = jerry seinfeld = comedian.
21 across: Dispose of vampire Dracula’s admission? (6)
Fantastic, awesome, hilarious, and all within the same semantic range. How would you kill a vampire? Via an impaling. And Dracula doesn’t get to see much light, so dispose of vampire = impale = I’m pale = Dracula’s admission.
