Canton, Ohio (CNN) - Apparently "Etch-a-Sketch" is the campaign gift that keeps on giving.
Nearly seven months after the children's toy entered the 2012 political lexicon, Vice President Joe Biden has continued to use the line on the stump - often with a fresh shake.

Case in point: as Biden campaigned in Ohio Monday, he referenced a claim first leveled by President Obama - that Romney's $5 trillion tax plan amounts to a "sketchy deal."
"As vice president, it's not my job, nor am I inclined to correct the president," Biden joked. "But in this case I am. [Romney's] plans aren't sketchy - they're Etch-a-Sketchy."
And then, Biden added a biting twist.
"They're like shaking that little tablet out there. It's underway guys. We are seeing the remaking of Mitt Romney right before our eyes."
The vice president leveled the charge in front of a crowd of nearly 900 people in Canton. The event was his first of five events over three days in the Buckeye State – a critical battleground. During one of the appearances, on Tuesday, Biden will make a rare, joint campaign appearance with the president in Dayton.
Although the Obama campaign has recently claimed Romney's economic plan is not mathematically possible, the Romney campaign has argued that it is.
"It is mathematically possible," Romney running mate, Rep. Paul Ryan, said in his debate with Biden, echoing similar sentiments from Romney.
The Romney campaign has also repeatedly denied that Romney is recasting himself and has said the candidate has been consistent in his positions.
