I've run into "Catholics changed the ten commandments".
It must be pretty common as there are several good Catholic apologetics articles online.

Recently a neighbor told me that "Catholics pay to go to confession".
(My confessor is still waiting for his check )

Catholics worship idols.  Why else do they pray and kneel before statues, pictures of dead people?  The pachamama is a prime example.
Catholics don’t read the Bible. Just ask any one of them to recite key verses, like John 3:16.
Catholics added noncanonical books and verses to the Bible.
Catholics rely on their good works to get to Heaven instead of the grace and forgiveness of Jesus Christ by His shed blood on the Cross and Resurrection from the dead.
Catholics blindly follow their Pope.  They’re supposed to believe he’s infallible!
Peter wasn’t appointed Pope by Christ.  He was merely one of three disciples in Jesus’s inner circle.
Catholics directly disobey Christ by calling their leaders, “father.”
Catholics have Mary into a goddess when she was simply Jesus’s earthly mother.
Catholics worship Mary and believe she forgives sin when Paul specifically states there is One Mediator between God and man, the Man Jesus Christ.  Catholics commit the same sin when they pray to so-called Saints.
The Catholic Church is full of child molesters, ɧoɱosɛҳųαƖs, and lesbians.  The reason for this is that they refuse to acknowledge that people have sɛҳuąƖ needs and the right to have them fulfilled in marriage.  
The Catholic Church is filthy rich and sits by as nations starve.
The Catholic Church actually preaches it has a monopoly on Truth; that it is the only way to God, when Jesus said “I am the way, the truth, and the life.  No man comes to the father but by me.”
Catholics say it’s okay to drink and smoke.  The Bible says our bodies are temples of the Holy Spirit.
Catholics unScripturally categorize sin by dividing sin into mortal sins and genial sins.  Mortal sins keep you out of Heaven but genial sins, God looks the other way.
Catholics believe in two unScriptural places called Purgatory and Limbo.  They think a person get into Heaven after death by spending time in Purgatory.  They believe unbaptized infants who cannot have committed any sin go to a part of Hell called Limbo.  There’s no suffering there, but they don’t see God, either.
Catholics wrongly baptize infants as if they can knowingly take Christ as their Savior.
Catholics are supposed to believe their Communion is the literal body and blood of Christ instead of taking John chapter six as symbolic.  In reality, very few Catholics believe this anymore.
Catholics confess their sins to a man instead of to God.  
Catholics must pay their priests for hearing confessions and other spiritual ordinances, thus forcing the poor to go without spiritual nourishment.
The Catholic Church is responsible for the deaths of tens of thousands of innocent people in the Inquisition.
The Catholic Church finances the Democratic Party in the USA, and if it could go back to medieval times, would be both church and state under an unelected and tyrannical Pope.  (Who will in the future, be what Revelations calls the AntiChrist.)
I could go on and on!
