Mine would have to be at my bachelor party. The experience was great, but I was fucked up. It was an all weekend bachelor party at a campground. Friday night was pretty relaxing, only had 20 beers that night and stayed up till 3am. Woke up at 5am to go fishing. By 10am was already another 20 beers in. So I decided to switch to rum. Drank a full forty before 5pm. Don’t remember the rest of the night. Woke up Sunday morning with the worst hangover. Three years later, I am finally able to drink rum again.
