בבא בתרא קסז ע"א
ההוא שטרא דהוה חתים עליה רבא ורב אחא בר אדא אתא לקמיה דרבא אמר ליה דין חתימות ידא דידי היא מיהו קמיה דרב אחא בר אדא לא חתימי לי מעולם כפתיה ואודי א"ל בשלמא דידי זייפת אלא דרב אחא בר אדא דרתית ידיה היכי עבדת אמר אנחי ידאי אמצרא ואמרי לה קם אזרנוקא וכתב
Bava Batra 167a
There was once a contract that had the signatures of Rava and Rav Acha bar Ada as witnesses. They brought this document before Rava to collect the debt.
Rava said, "That's definitely my signature, but I never signed a document along with Rav Acha bar Ada in my whole life!"
They pressured the bearer of the document and he admitted that it was forged.
"I get that you were able to forge my signature," Rava said, "But how did you forge Rav Acha's signature? His hands are constantly trembling!"
"Easy!" the forger proclaimed. "I stood on a shaky rope bridge and signed it!"
Today, we are often taken aback by how crooked people are. You can hardly walk down the block in Manhattan these days without someone trying to scam you. Unfortunately, this is not a new phenomenon. Scammers have existed since the beginning of time, and will always be around.
