Smell my......

Recently Justin walked into the living room where I was relaxing and reading the paper.  Bruce was in his chair watching TV when Justin came into the living room whining about his finger.  He was looking at it and I had assumed he had hurt it.  Instead he walks up to me and tells me to smell it!  Bruce and I burst out laughing and I tell Justin I am not going to smell his finger.  Then I told him to ask his Dad if he wanted to smell Justin's finger.  Justin kept insisting I smell his finger.  Not sure what he got into and what it smelled like (because I never did smell it), but it was funny.
