lol he couldn't drink the coffee because he didn't have a second hand to pick it up. That's so funny. They should have the one armed man on the show while people laugh, that's how funny it is. He should be invited to laugh at this gaff. To laugh at himself -- because he only has ONE ARM.

SO FUNNY. SO FUNNY -- BECAUSE HE'S MISSING AN ARM. hahaha! HAHAHA! HAHHH! *dies of an aneurysm*

true story: the other week there was a student on crutches at the cafeteria, and when he got his food, he was struggling a bit carrying both the food and the crutches and hopping along. So a cafeteria worker comes along, offers to help, and takes his crutches instead of the food...
The student politely asked the worker to switch, and they went on their way.

I was waiting for the jerk to tell him "drink up!"

Some people don't really think about when deciding to help someone. At least they made the decision to help...

I think the joke is that the coffee server is a bit of a thoughtless asshole. Nothing to do with making fun of the man's disability.

And why didn't the one armed man put the saucer down and pick up the cup. It's not like this is his first day with one arm.
