Most people don't realize that the astronauts staying on that space station or shuttle sometimes have a problem with the smells.
Upon opening the door on the shuttle, one guy told the press that it smelled awful. To confront this, one lady took 6 of those little cedar tree air fresheners.
On the return the guy opened the space shuttle and almost passed out.
"What's the matter", she asked. "Is the smell still bad?"
"What does it smell like?"
"Like somebody shat a Christmas tree."
