Hey, you raised 'em. (Via redditor imn8bro)
Best Man speeches pretty much come in two varieties. There's the all-about-me speech, which includes some variation on, "As some of you here know, I've been going through some hard times, but Jeff was there for me when I needed him!" That's the downer speech, where the Best Man all but holds up his 6-month AA chip for everyone to see.
The other one is the "humiliate the groom with horrible stories of debauchery and pretty much tell the bride he probably gave her HPV by now" speech. We can be pretty sure that's the speech that was given by redditor imn8bro at his brother's wedding, based on this instant classic of a pic that he shared yesterday.
