Li'l Bastard is a company which manufactures various kits designed for nefarious deeds. Their product line includes
- Li'l Bastard General Mischief Kit, which Bart attempts to use in "The Joy of Sect"
- Li'l Bastard Brainwashing Kit, which is successfully used by the Movementarians in "The Joy of Sect"
- Li'l Bastard Clock-Tampering Kit, which Bart regrets using in "The Boy Who Knew Too Much"
- Li'l Bastard Traveling Kit, which contains a stink bomb Bart uses in "Itchy & Scratchy Land
Most of their products come in a dark carrier case with the company name and kit name in orange on the front.
For some reason, the clock-tampering kit uses a hyphen for the compound adjective, but this is not the case for all kits.
