Nathan Fielder's latest Twitter text prank might just end your relationship.

The Canadian comic, whose phone pranks are well-known, asked his followers to conduct a little experiment with their boyfriend or girlfriend on Wednesday.

"Text the person ur dating 'I haven't been fully honest with you' then dont reply to them for 1 hr (& tweet pic of thr response)," Fielder tweeted.

The results were predictably hilarious, though fair warning that many of the responses are pretty explicit. See the most hilarious tweets and screencaps in the slideshow below.
