1. Nick lewis's grinder
2. Take grinder home and take wheel and tire off bike
3. Take inside bathroom
4. Place on the bottom of shower cubicle
5. Get extension lead into bathroom
6. Place one foot on it
7. Grind to f00k
8. Shout rest of day because you deafened yourself because u used a grinder in a tiny little en-suite bathroom at uni accomodation.
9. Stand back and enjoy what you have done with a beer and smile at the fact you just woke all your flatmates up :D
10. Still have lewis's grinder because he got hit by a tram so didnt feel like picking it up.
