Pagliaccio is clown.
Scaramuccia is also a clown - a “little skirmisher”
From wikipedia...
“Scaramuccia (literally “little skirmisher”), also known as Scaramouche or Scaramouch, is a stock clown character of the Italian commedia dell’arte (comic theatrical arts).”
And boy does that name fit Scaramucci. He came in and immediately started his clownish “little skirmishes”... and quickly lost.
