If you don’t take care, your friend Bunbury will get you into a serious scrape some day.
Foreshadowing
They are approaching. That's very forward of them.
Pun

Ask Mr. Bunbury, from me, to be kind enough not to have a relapse on Saturday.

Allusion
Horrid Political Economy! Horrid Geography! Horrid, horrid German!
