If above user's avatar showed up on your doorstep...

[Dr.Susse]

I'd tell them to belive it and try to convert them to the church of sleeping in.

 

[Sacman]

I would tell them I already sleep till 2 everyday so it doesn't matter...

 

[Xpwn3ntial]

Close the door.

 

[AwesomeExpress]

Give them a book mark.

 

[AgDr_ODST]

damn another sticker stuck on my porch

 

[Zeromaeus]

What's with that armor anyway?
-pokes with cane-
Doesn't look like it would deflect spells all that well.

 

[Xpwn3ntial]

Invite him in for a conversation.

 

[Dr.Susse]

Tell them to come in out of the wind.

 

[Scde2]

Call the tow truck.

 

[SixWingedAsura]

Call the Hellsing Organization.

 

[Xpwn3ntial]

Find Xandus 117 and enact a Highlander duel.

 

[Sacman]

Spoiler: Xanadu?

I would invite them in to play some games...

 

[Zeromaeus]

Thundara!
-lightning strikes the television-
-The flickering stops-
Well, at least it works properly now...

 

[AwesomeExpress]

Yoink! I got yer hat now!

 

[Zeromaeus]

Give it back or else.
-points cane-
This is your only warning.

 

[Martin Toy]

Ask this fine fellow in for a glass of brandy and a cigar.

 

[Zirat]

Invite him in for the party, he seems to be a cool dude.

 

[xmbts]

Well normally I wouldn't allow corpses on my doorstep but I'll make an exception just this once.

 

[Zeromaeus]

Welcome to party, good sir. Mind yourself and don't kill anyone. If the blood-lust should overcome your sense there are monsters in the basement. Now enjoy yourself, as we will continue until midnight of the thirty-first.

 

[xmbts]

Well technically my avatar is a girl but I can forgive it since such an adorable looking little person is on my doorstep.
