Gift trouble?

This might be a ridiculous question/thread but I'm having some trouble making a decision on my own. My good friend's 21st birthday is coming up and I have no idea what to get him. I have narrowed it down to four different choices, three of them having to do with the idea of drinking and one having to do with drinking (again but with coffee not alcohol). My friend does not drink extremely often but does occasionally drink beer with his roommate and the same goes for coffee. The first choice is the Minibru Coffee Mug. The mug is basically a mug-press hybrid that lets you enjoy your coffee right out of your French press. I considered this one because he does drink coffee when he is feeling exhausted and it is something that he could use later in the future. The second choice is the Hopside Down Beer Glass. The Hopside Down Beer Glass is a glass with the optical illusion of an upside down beer bottle inside of it. I tried inserting links and pictures into this post but they didn't work out so my apologies. I like this choice and the next because they are both more on the fun side and I felt its appropriate to give him something having to do with beer because he is turning 21. Another reason why I would consider this choice and the third is because the cups could also be used for beverages other than beer. The third choice is Beer Shot Glass. Which is basically a similar design to the Hopside Down Beer only it can double as a cup and a shot glass. And last but not least the fourth choice are Whiskey Stones. I'm not too sure how I feel about this one because I'm not too sure about how often he would put them to use. If you were a 20 year old turning 21, which gift would you be most happy with? Or which gift, in your opinion, would be the best gift to give to my friend?
