I tried this a few times already this month it gets alot of laughs Is a great neg and can lead into a nice convo.
You say "hey so I'm growing my moustache out for Movember... I see you are too... It's coming along nicely I'm impressed"
Words to that effect. You don't have to use the whole line you could just stop at I see you are too.
You can go on to talk about the cause your supporting ect.
What you guys think?
