The South Korean comedy TV show "Gag Concert" had a series of sketches called "I'm a Killer", in which a group of incompetent assassins attempts to kill a rich guy (Yu Minsang) but always fail hilariously.
One of the assassins, a woman, palyed by Kim Ji-min, get messy in her several attempts. The individual segment are on YT with English subtitles.

1) Kim Ji-min leans her hands on a table with a cake only for the table sheet slips, causing her to fall and plant her face into the cake.

Apart from Kim Ji-min, there is also a trio of male assassins who often accidently kill themselves is some messy way, e.g. dump "poisonous" green slime/powder all over themselves and so on.
