Well, there is dna on the blue dress, just saying.
I would be delighted to buy Billy Boy Clinton a drink so long as I could keep the glass for DNA analysis. I suspect it would be amusing in more ways than one. Perhaps in many ways if Web Hubble would also have a drink and give me the glass.
This will not happen.
For myself anyone can buy me drink and keep the glass so long as the drink if a good single malt scotch or Irish. Actually the Irish is good even a blend. It is nice stuff.
