I like this super modern rendition of an old fashioned flask.

After dating my budding career in high school, my college education included a 30-something Italian boyfriend, and in a few years I graduated to a 40-something financier closer to my dad's age than mine.

So here's a flask for Father's Dad's Day. (via ThisNext's Blog)

Looks like a stainless steel donut.

If you're going to drink, you might as well look good doing it.
