We've heard of brothers teasing sisters but not like this!
It started with:
Not according to this fan-made video!
Charlie was making his way to Taco Bell for some grub when a fan in the drive-thru called him over to record a video of their encounter.
Little did the man know that Charlie would admit to being "hammered."
Let's just hope this doesn't lead to another public downward spiral for the former Two And A Half Men star.
