And that was still the case on Friday’s for the studious brunette on the Channel 4 show.
However, the TV star fell victim to an innuendo as she discussed the history of jugs.
Susie was seen raising a smile as she announced that she was going to be delving into the meaning of “jugs and mugs”.
Susie managed to contain her composure as she told the audience that jugs used to be called “Jack and Jill”.
She also revealed the term mug came from Scandinavia.
Interesting stuff, right?
As well as the naughty moment, show fans were also treated to a racy outfit from Rachel Riley.
The blonde wore a cut-out dress, which showed off her curves perfectly.
The dress also gave fans a glimpse of the star’s bare back as she turned around to write on the board.
What a little minx.
Rachel also discussed her participation in bicycle race Ride The Night UK this weekend.
The event sees women ride 100km through London at night to raise money to fight cancer among females.
