Which do you say?

[Hobgoblin]

I tend to say gesundheit.

 

[Duke]

Bless You.

 

[Rocketman]

I do this weird thing: "Blesh-ooh."
Or "Bleh-Shoe."
It makes absolutely no sense, but I've always done it.

 

[The Squirrel]

Bless you twice, and if it makes it to a third time it's Gesundheit.

 

[Ultra Lantern]

Bless you.

 

[Snare]

Nothing

 

[Drizzle]

Stop sneezing.

 

[Scarlet spidey]

I usually just glare at them and tell them to knock it off.
I do this to myself if a mirror is around.

 

[Sawyer]

I say "You Deserved It".

 

[Aesop Rocks]

I dance around and shout wolf gang.

 

[Why Are You Crouching Spock?]

"Cover it with your hand" usually.

 

[Master Chief]

Good job.

 

[Kane52630]

I say "Zip It Up and Zip It Out!"

 

[ProjectPat2280]

You're sooo good looking.
