•In Batman Returns, the Penguin has a gun in his umbrella. And a sword. And a helicopter (try and wrap your mind around that one). A later scene implies that the Penguin has an entire arsenal of different weaponized umbrellas, but he's only seen with one at a time and only exchanges umbrellas in that one scene. Either the Penguin keeps two more umbrellas hidden in his coat, or his standard umbrella functions as both a firearm, a melee weapon, and a personal aircraft.
Seen in Iron Man 2 when Whiplash escapes from prison with the help of someone sending him plastic explosives that look like his normal cafeteria food, with a note to "enjoy the potatoes."
•Parodied on the Spongebob Squarepants episode "Spy Buddies": among SpongeBob and Patrick's spy gear are Spongebob's 'coin operated' pants-phone and Patrick's laser shorts, which mess up and fire everywhere when he has to go to the bathroom.
In the Gravity Falls episode "The Time Traveller's Pig", Blendin Blandin's time machine resembles an ordinary tape measure.
