There is no subtle way to give somebody a bottle of Scope... (Ann Landers)
A couple of years ago we hosted a Japanese teacher for a year. He was here to teach in the high schools in an exchange program. He was a nice guy, but had very bad body odor. Problem was he showered regularly, but didn't use deodorant.
We bought him some and told him why...
On a side note, he was the original stuntman for the Red Power Ranger!
