A Roast Beef Sandwich Bath Soak? So now my entire body can smell like roast beef? Count me in! Not really! This clever prank won’t really make you smell like roast beef, but the person you gift it to will believe it. What you really get inside is 23 ounces of therapeutic Mediterranean sea salts that smell like brown sugar and fig. That’s much more pleasant. This is sure to gross someone out and give you all a laugh.
