Last week we had the Virginia legislator who did this:

To protest a bill that would require women to undergo an ultrasound before having an abortion, Virginia State Sen. Janet Howell (D-Fairfax) on Monday attached an amendment that would require men to have a rectal exam and a cardiac stress test before obtaining a prescription for erectile dysfunction medication.

The amendment ended up being a symbolic gesture as it was defeated and the original bill was passed.  This week we have this story from Indiana:

Rep. Jud McMillin, a Republican member of the Indiana General Assembly, took back his drug-testing bill after one of his helpful Democratic colleagues amended it ever so slightly.

The Huffington Post says Rep. McMillin, the sponsor of the bill advocating a pilot program for welfare applicants to be drug-tested, decided to withdraw it once his colleagues made a few tweaks.

"There was an amendment offered today that required drug testing for legislators as well and it passed, which led me to have to then withdraw the bill," he said.

His reasoning is that it's currently considered unconstitutional to require drug testing for political candidates, and he wanted to make sure the bill wouldn't be struck down because of that. However, the precedent involved was for candidates, not those already in office.
