Will having my friend peeing in a condom in my car right before drug test work?

I have a pre employment test in two days. I will piss hot but I have a sober friend who can pee in a condom in my car directly before I walk in to take an unsupervised drug test. I was thing about wearing compression shorts and immediately put condom in my gooch and walk in. Will this be enough to keep the piss warm enough?
