I’ve fallen and I can’t get it up! 

The more current, commonplace version of the old saying now that folks don’t necessarily need to be able to ambulate well in order to fuck.

I don’t know what happened, I took my Vitamin V and now I’ve fallen and I can’t get it up!

I've fallen and I can't get up 

A really annoying catchphrase from the late 80's/early 90's that originated from a commercial for a paramedical emergency radio for the elderly. During the commercial, and old lady falls off her walker and in the most pathetic tone of voice possible, utters this phrase into the advertised device.

Before everyone and their mom was screaming "I'm Rick James, bitch" they were screaming "I've fallen and I can't get up" in a sad attempt to be funny and witty.
