How I know you stopped listening

[braindead]

Yesterday I had one of those people that should have made me angry but the situation was just so funny.

I am answering the guys questions no problem for a short time. I finish up with his last question, I stop talking. Well the guy kept saying Yeah, uhhu, yeah. This went on for a good 30 seconds before I finally pipe in with ok then I will let you go. He then goes Ok and hangs up.

I swear this cracked me up for the rest of the day.
