Well as hard as this may be for some on this site to believe I've actually been the best man three different times for three different guys. It's possible that if a certain other three guys ever get married I'll be their best man as well...... Always the best man never the groom

First of all chill out   It's not hard. It doesn't have to be complicated. You don't have to do much. Plan the stag. That's your #1 job. You don't have to do it alone though. Get the other guys in the wedding party to help AND ask the groom what he wants to do.  If he has something in mind go with that, just don't put the burden of planning any of it on him. Unless he wants to.

Secondly you'll probably have to do a speech of some sort. This is the scariest part for some people. For me it was a piece of cake and in all honesty I never prepared anything either time. I simply got up there an spoke with a goal in mind. First time I was going to make people laugh. Done. The place was like a comedy club. The second time I decided to make everyone cry. Done. Waterfall central. The last time I did a little of both. All three times were easy for me because I had a "goal" in mind and just winged it. Speaking in front of people has never been an issue for me and I've been doing it since highschool so..... I didn't worry about  what I was going to say only what I wanted to convey. Not sure if that aproach will work for you but it's an idea.

If giving a  speech is freaking you out my advce is to keep it simple. Keep it short. And keep it real. Nothing is worse than listening to someone give a speech that is out fo character for them and feels forced. If you're a serious guy, be serious. If humor is your thing do that. Don't be something you're not. You want it to be genuine not scripted. Make sense?

Other than that when his bride starts getting crazy he'll start to get crazy as a result. She'll also have a lot of stuff to do with her bridemaids leading up to the wedding day so there will be lots of opportunity for guys nights out. take that lead. Notice when the bride is occupied and get the guys together. Once married those opportunities come along less often, especially once kids enter the equation.

Not gonna lie that jacket Jon is wearng is pretty cool.

Also I'm conflicted. I can't tell if I think Miley Cyrus is hot or not.

Did people mock Axl's physical appearance back in the day? Maybe his fashion when it came to what he wears on stage but wasn't he always looked at as a "hot" guy? Maybe I'm wrong but I remember a lot of girls back when I was in highschool thinking he was fucking hot. Can't imagine people made fun of his physical looks to the point he needed to go under the knife

Yes he has. It's plain as day that something changed between 1998-2000. Obvious plastic surgery
