(heh, the "proof" is actually 100 for Old Grand-Dad whiskey)
There is almost nothing I won't hot glue to a hat in service of a theme. This year, that included a pint of whiskey (heavier than I expected, but pleasantly more structurally sound than I feared it would be) and fistfuls of fresh mint.
Yes, I did end up eating and drinking my hat by the end of the night. You can't say I wasn't prepared.
