No cookie again

I used to have a real problem with sweating alot, but made sure it was clean sweat, sometines changing shirts three times a day and constant washing and use of deoderant.

I have a friend that wants to come to Whitby with me and stay in my camper van. The problem is that he smells of old sweat. When I suggested to him that a wash wouldn't go amiss, he laughted and said it was a good manly smell. Well its not. Any ideas on how to proceed, all you wise catters out there. Any sweaty songs?
