Unusual Greetings
From Homestar Runner Wiki
Weclome
Weclome is a word which has appeared a couple of times on the Homestar Runner website. Its first appearance was in 2 emails, when the welcome banner for the Ladies' Choice Awards was misspelled as "weclome".
This misspelling later appears in Malloween Commercial, on Homestar's doormat. Possibly (though unlikely) as a tribute to the great Scottish comedy, Still Game, which based a season one episode on the purchase of a Weclome doormat.
In an episode of G4TechTV's "Pulse," they interviewed the Videlectrix CEO (Matt in disguise), who greeted them with a hearty "Weclome!"
Helscome
Helsome was first used on Homestar's Website
Later, on the DVD commentary for Tis True, Pom Pom, Tis True, "helscome" is used again by Mike Chapman.
Haldo
Haldo was first used in Peasant's Quest, in which Mendelev has Rather Dashing tell Dongolev "haldo".
It was later used on Quote of the Week. If there is a problem finding the weeklies.xml file, the text (which has no sound) is Homestar Runner saying:
"Oh Haldo! This is my
funniest word style
ever times that I've
said! Hope all is on
to it even more
lately! And I wish the
chicken & msg place
was open on
Somedays."
