Heime is right:

  (defun do-something (arg)
    (cond
     ((eq arg 'this)
      (message "yes, this")
      (message "did I say this?")
      (message "yes, I said"))
     ((eq arg 'that)
      (message "what was that?")
      (message "this example gets boring"))
     (t
      (message "what?"))))
  
  (do-something 'this)

Besides, the doco says that a clause returns its last espression's
value, so it does behave like many little progn.

Cheers
