Im screwed

i have been on probation for 6 months adn have been clean for 3 months and smoke like n eight in the last week and now my p o is coming tom and i gotta drop if i pass i will be off probation if i fail i go back to jail so i ask my friend and hes gonna give me his piss but my question is if i tape a condom to my nuts will it stay warm for like 4 hours

get a digital thermometer or child's temp strip and practice yourself beforehand. Use water in the condom and get it to 100 degrees (or higher). Practice giving the sample and take the temp of the sample in the cup. Keep checking and see how long it takes to drop below 94 degrees.... this will give you your answer.
