Bäst i Test kicks off with bathtub-draining, Icelandic firemen and scary dairy. Kalle Zackari Wahlström sits in as the first guest contestant.

Actress Eva Röse joins the cast this week to see who can best avoid blinking, paint a horse, move a potato and find all of the Finns.

This week, guest contestant Parisa Amiri and the rest of the gang must impress an 104-year-old, shoot a film in reverse and buy a special gift for the Taskmaster.

Markoolio is the special guest for this week's grand final, in which the contestants must stage a home movie blooper, transport a boulder and get a train to honk its horn.
