I once had the Tesco (a British supermarket chain) own brand spicy pasta sauce. It sure was spicy. So much so that I had to stop eating the food as my tongue would not stop tingling.
The pain didn't stop there though. The next morning, I went to partake in an evacuation and the fire was unbearable. When I finally finished, it was far to tender to wipe. The only recourse, was to jump into the shower, turn the cold on full and point upwards while straddling the shower head.
First time I ever cried while having a poo I think.
I don't believe said sauce is on sale anymore.
P.S. 2 tubes of Pringles in 1 hour has a diarretic effect. You have been warned.
P.P.S. If you bet your brother that he can't eat a bright orange mexican chilli and he accepts. Keep some milk and light chocolate on standby. Beer will not have the effect that he is looking for no matter how funny it may be to me and my mates.
