Input: Text: i had just come home after school expecting that my older brother to have mowed the lawn like he said he would the night before. surely enough nor the front and back yard had been done, so i told my dad and mum that i would do it. so i begin to prepare myself, put my earphones in, get my hat, then go and get the mower. i pull the mower out of the shed and get the canister of petrol, paying no attention to my actions i unscrew the cap off the oil tank and begin pouring petrol in. i end up putting quite alot of petrol in, fix the cap back on and start the mower. it is working fine for 4 minutes but in that 4 minutes it is just puffing out smoke continuously and clicking in an odd manner. i stop the mower and then realize what i had done, so i get the petrol canister and pour some into the petrol tank thinking "year itl work fine now"...the mower doesnt start at all, so seeing as i had realized my mistake i tip out some oil hoping the petrol will go with it. i try the mower again but it wont start, by this point i though "fuck it, ill get dad" i tell him it won't start and why i think, he repeats about 4 times "yer that'l really fuck it up" we go outside, he tries and ask me how i managed to do such a thing, i try to mumble 3 bullshit lines but ends up being nervous dribble. 

in the end he managed to pour all the oil out and replaced it. i mowed the rest of my half then my brother came home and mowed the rest, but will never put petrol in an oil tank again...i hope

TIFU by pouring petrol in the oil tank of the lawn mower
