Fatfree Root Beer Floats

2 scoops fatfree frozen vanilla yogurt or ice milk
16 or larger bottle Diet A & W Root Beer

Pour 1/2 c or so in the bottom of a large glass, add the frozen yogurt,
let the carbonation settle down and slowly add rootbeer until the glass
is full.  For those who are near a Crate and Barrel, our local store
had large thick glass beer mugs for about $2.75 that I got wet and put
in the freezer for about 30 minutes before making the floats.  Be sure
the root beer is very ice cold before using.
