Concerned/YMMV

"Frohman: Whoa! I guess I actually went completely nuts with it. Just hope the next guy to use it doesn't see my lip-prints all over it."
 * Cargo Ship: With the gravity gun.

"Frohman: Ah-hah! Didn't think you'd ever see me again, eh, "doctor"? Now if you'll excuse me, I believe I hear a stunstick warming up, and for once, I won't be the one getting hit by it! (Behind Frohman, the mook has removed his helmet and revealed himself as Barney)"
 * Crowning Moment of Funny: Several throughout the series, but one of the best is when Doctor Breen tries to force choke his soldier. See You Have Failed Me below.
 * Frohman finds out that the metrocops are looking for a certain scientist. Recognizing Dr. Kleiner from the description, he (not so) immediately finds a mook and leads him to the doctor's lab.

"Barney: Get ready to start a new chapter in your life. It's called point insertion and it features this stunstick in an unforgettable starring role!"
 * From the following strip:

""Dear Dr. Breen. Help! I've been taken prisoner by an alcoholic and a stereotypical absent-minded professor! Send Striders!""
 * Also, the "apology letter" and Frohman's evil faces that follow.


 * The Combine's Onion-like attempts to cover up Freeman's massacre at Nova Prospekt.
 * Frohman's interactions with water mines, particularly here, are always hilarious.
 * The notes for this comic.
 * Hilarious in Hindsight: In one set of notes, the author bemoans the Mets' loss to the St. Louis Cardinals but figures that they'll probably get steamrolled by the Detroit Tigers anyway. Not quite...
 * In addition, much of the game itself, if one considers the comic to be canon, turning it from an epic drama into an epic screwball farce.
 * The last strip. Yeah, it's "The Life and Death Of Gordon Frohman", but fans were still genuinely upset in the forums about Gordon's demise.
 * He's Just Hiding: Despite reading the title, many loyal readers were outraged and in denial once poor Frohman finally got offed.
 * Concerned 2, an unofficial sequel, revealed that Frohman was brought Back From the Dead by simply re-loading from the last checkpoint.
