I'm going to get my friend drunk
What is causing you to want to get your friend drunk?
It will be funny to see him drunk.
Alcohol is unhealthy and you should not get your friends drunk. Getting your friend drunk could cause him distress.
Are you just saying this because you want to drink with me?
While it can be fun to get your friends drunk at times, I would still use some discretion. Not everyone is able to drink alcohol in moderation, and sometimes when that happens the person can get pretty sick. I would be aware of it and just try to think of their health.
