              Mark sounds like smeagle like kinda expect him to say "my precious " while maliciously looking at Ethan

                        ETHAN SOUDNS LIKE MOANING MYRTLE!!!

                        When they are talking about Abigail, ethan sounded exactly like moaning myrtle. It hit me at 1 in the morning when I woke up to get water

                          And I exited.” 🤣

                              This video of white noise and smooth jazz was nice, except for the occasional laughter that could be heard in the distance. 3 stars.

                                Hearing about Mark's first time was so cringe and awkward to listen to.

                                            Imagine if Ethan took on a girly personality while talking to markiplier. That would have been hilarious.

                                                  Markiplier could be the voice of Salad Fingers. Without the helium he could voice a very furry alien from Melmack.
