So rugby referee Nigel Owens got sprayed by "Jiffy", and reacted in much the same way he does when dealing with juvenile antics on the pitch.
Quickly recovering his composure after being forced out of his car by the cloud of foam, he calls Jiffy an "idiot" in his authoritative "referee" voice. Jiffy and his co-conspirator were too busy laughing at their exploits to take much notice.
The video quality is absolutely awful, but his assailant can only be BBC pundit and Wales legend Jonathan Davies, who goes by the Twitter handle of @JiffyRugby.
Also, I must have watched the first 15 seconds of the video about ten times trying to figure out what they were saying, especially considering the fact that somebody has transcribed the dialogue in the comments section of the video. Unless I'm particularly deaf this morning, they were speaking in Welsh.
Owens has since tweeted a link to the video, which suggests that he was pretty OK with the whole incident, or at least he is now.
Here you go then as you have asked. Here is Jiffy's prank on me with Sarra Elgan filming it on the sly lol https://t.co/KiUIA68ynM"
