Claire is told that Gabriel's friend tripped on a dose of 'fry', aka 'wet', a combination of embalming fluid and fertilizer. 'Fry' is an existing (and highly deprecated) drug, but it is made with PCP, not with embalming fluid or formaldehyde.
Trevor's wife refers to her appearance on Politically Incorrect (1993) and adds that the "emaciated chick" from The Practice (1997) was also on the show with her. This is presumably a reference to the show's star, Lara Flynn Boyle, who is well known for her often very skinny figure.
