Chico Flores of Swansea went down clutching his face after a challenge with Carlton Cole. Allardyce, who saw there was nothing in the incident, laughed in the face of the defender.
For a moment, it looked as if that would lead to a confrontation between the pair, but Angel Rangel stepped in to usher his teammate away before things escalated.
The moment works best as a Vine, so enjoy this footage on its six-second loop (we suspect you'll want to see it more than once).
