From listening to the story it seems that this guy was driving around in his car with the 38 shoved up where the sun don't shine.
Do you think that he lost a bet or was he just trying it out for size?
'He man, I'll bet that you can't shove that gun up your behind and drive down to the liquor store and pick us up some more beer!'
Maybe he wanted to get arrested so he could smuggle the pistol into the jail? Perhaps he should have looked for a snub nose instead?
