Return Value from Powershell Function

At the risk of asking a "silly" question..  I would like to know the "best practice" for "returning" a value from a PowerShell function..  There are several different ways that this can be done..  I would like to have two different variables to be re-usable elsewhere in the script..

# http://social.technet.microsoft.com/Forums/en-US/ITCG/thread/4da65aaa-f261-4d7c-8726-d7613f56d0eb/
#[PowerShell] - Return value from a function
Function showval
{
$val="keeper"
#Return $val
$val2="forkeeps"
Return ,$val,$val2
}

$ReUse = showval
#Method 1 - ForEach
$ReUse | ForEach { `
  "Item: "+$_
  }

#Was thinking of how to implement a counter for the variable
  #Get-Content foo.txt  | foreach { '{0} {1}' -f $_.ReadCount, $_ }

#This also works..
# Foreach ($Reuses in $Reuse) { `
#  "Item: $Reuses" `
# }

#Use of split works too..
#Write-Host "ReUse "$ReUse # shows: keeper forkeeps
#$dnstream=$ReUse.Split(",")[0]
#$dnstream1=$ReUse.Split(",")[1]
#Write-Host "value1 "$dnstream # shows keeper
#Write-host "value2 "$dnstream1 # shows forkeeps

here's a simple example:
function returnMV()
{
$data = @()
$data += (Get-Process | select -first 1)
$data += Get-Date
$data += "jonny brown"
return $data  
}

$returnvalue = returnMV
$returnvalue[0]
$returnvalue[1]
$returnvalue[2]

in youe case:
Function showval
{
$data = @()
$val="keeper"
$data+=$val
#Return $val
$val2="forkeeps"
$data+=$val2
Return $data
}
