Location of a messagebox?

Hey, I'm new to coding, started yesterday. Been experimenting and i'm now trying to make a scare program, basicaly when they click a button, it screams, and displays tons of message boxs, Is there a way to set the position of the message box? so I can make random variables have have tons of messageboxs popping up all over the screen?

s Form1
    Dim TimeGoneBy As Integer = 0

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Timer1.Start()

        My.Computer.Audio.Play(My.Resources.funny, _
    AudioPlayMode.Background)

    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        If TimeGoneBy >= 0 Then
            MessageBox.Show("Spam")

        End If
    End Sub

    Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click

    End Sub

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    End Sub
End Class
