Passenger: (looks at watch, sees that it's not nearly time to leave, scoffs; then passenger gets hit by man carrying wooden boards, twice)
Train Conductor: Told ya. Warned ya twice.
A subtrope of Slapstick and Amusing Injuries, this is an old gag where Alice is carrying long items such as planks, logs, poles, or ladders, turns around and accidentally hits Bob, who was standing behind or next to her.
This happens either because Bob called Alice from behind, and she instinctively turned around to greet him, or because she wasn't aware of his presence, or simply because Alice isn't careful of her surroundings.
One common variant is to have the carrying character unknowingly knock out an attacker that was furtively approaching from behind. Another is to have a sufficiently quick-witted character duck the first swing, only to be clocked in the head when Alice turns back around.
This gag find its origins in Vaudeville and Music Hall, leading to its use in the Silent Movie era. Virtually every silent movie, starting from Chaplin to Laurel and Hardy, used this gag at least once, even when talkies came along. The Plank Gag was also a favourite of the Three Stooges. It's still used on stage today in the UK with Pantomime.
If you're thinking about a guy getting hit in the face by a board that he stepped on, that's actually a variation of the Rake Take. Also compare Nautical Knockout. A Plank Gag might be set up, but subverted by the Coincidental Dodge.
- An old Australian television ad for insurance has some average Joe walking along the street, narrowly avoiding accidents. One of the accidents he ducks (literally) is the Plank Gag.

- A Swedish TV ad for Vicks Blue cough drops has a man trying to call attention to a running purse snatcher, however his voice fails him. He's offered a pill, his throat clears, and he shouts loudly across the street where the man's escaping — "Stop the thief!!" Everyone turns towards him, including a man carrying a rafter, who accidentally knocks the purse snatcher out cold as he comes running.
- In Zoids: New Century, this plus a Coincidental Dodge enables Bit to unintentionally and unconsciously rescue Naomi Fluegel from two thugs by brutalizing them with a large pipe.

Naomi: Is this guy totally zoned out or did he do all that on purpose?

- Also common in kid comics like Spiff and Hercules. In one strip at a mountain resort, Hercules happily swirls around with a pair of skis on his shoulder. Spiff ducks under them, but a passerby gets hit in the face. The man grumbles "Do you think you're in a Mack Sennett movie?" and chases after them.
- Happens once in the Bone collection The Great Cow Race. One page has Smiley holding a ladder from one end while the other is between Lucius and Phoney.

The sailor spins, swatting Stepanek off the deck, thus successfully relocating him into the sludge tray that was alongside.
