In the scene where Ty is at Carl's room drinking wine and smoking the joint, Ty takes a drink from the jug with his hand at the bottom of the bottle. The angle changes and instantly he has it grasped by the neck. Otherwise he wouldn't have been able to put it down, as he had a golf club in the other hand!
Good eye, however there were more shots in that scene (and makes the scene funnier than the final version). The bottle comes into play which is why he goes from holding the bottom to the neck. The extended version should be released soon and it makes the film 100% more funnier (if that was even possible).
