                    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.
