Which biscuit almost caused a fight?

Until 1968 wives and girlfriends stayed away from Abbey Road during business hours. This unwritten rule was unilaterally abandoned by John. The new arrangement was to have “Yoko literally in the middle of the recording session...sitting on the amps" as Paul later put it.

According to Geoff Emerick, resentment exploded into the open during an infamous Abbey Road session. On this occasion a bed -  equipped with microphone - was introduced into the studio to allow the indisposed Yoko to participate in proceedings see video below.

The atmosphere was already a little frosty when George Harrison spotted something that sent him over the edge:

... he began staring bug-eyed out the control room window… Yoko had gotten out of bed and was slowly padding across the studio floor, finally coming to a stop at Harrison’s  packet of McVitie’s Digestive Biscuits.

George's watched with smoke coming out of his ears - out of his mouth, too, probably. 

Idly, she began opening the packet and delicately removed a single biscuit. Just as the morsel reached her mouth, Harrison could contain himself no longer. ‘THAT B**H!’ 

Everyone looked aghast, but we all knew exactly who he was talking about. ‘She’s just taken one of my biscuits!’
