(CNN)This campaign season, one thing is certain: insults will fly.
While debates have been the perfect venue for political mudslinging for decades, the addition of Donald Trump has certainly made things more interesting this time around. But don't forget the insults the candidates of yesteryear have contributed to the Debate Insult Hall of Fame.
Al Gore said George Bush "taking credit for the Berlin Wall coming down is like the rooster taking credit for the sunrise."
Just a few months ago -- and more than two decades after Mr. Gore's simile -- Republican presidential candidate Sen. Ted Cruz said of his opponent Sen. Marco Rubio, "For Marco to suggest our record's the same is like suggesting the fireman and the arsonist have the same record because they're both at the scene of the fire."
Then there are the subtle digs, like the time then-Sen. Barack Obama told Hillary Clinton in 2008 she was "likable enough."
One of the most notable debate moments came during a vice presidential debate between Sen. Lloyd Bentsen and Sen. Dan Quayle in 1988. After Quayle compared himself to President John F. Kennedy, Bentsen delivered one of the most famous comebacks of all time: "Senator, I served with Jack Kennedy. I knew Jack Kennedy. Jack Kennedy was a friend of mine. Senator, you're no Jack Kennedy."
For these moments and more, take a look at the video above.
