a bit embarassed to say... But on Seinfeld there was an episode where they said "You're soooooo good lookin'" whenever someone sneezed, so I did that for a while.
Its kinda weird, but I dont say Bless.. I say Blesh you.. I just dont feel comfortable going around telling ppl bless you..
'Excuse you' or 'Bless you'. I don't really care how it sounds like. I figure it's just meant to be nice/polite.
