what annoying photo effect is this?

The internet tells me that this was the pilot episode and starred Giovanni Ribisi.

Also: Blossom: Why is this happening to me?
Six: Because you're blossoming Blossom!

Tony was indeed a recovering alcoholic/druggie.
They used that as a launching pad for many a joke; Tony off hand mentioning some crazy thing he did in his wild days for a fast lol. always seemed sort of tasteless. WOAH.

one of the pictures in the girl's photo series says something about "whoa" in the title which is obviously a new clue as to her blossomness

ha a hha haa
