Nicky Southall grabbed a hat-trick as Nottingham Forest went on the rampage against sorry Swindon.
He put Forest ahead from long range after just three minutes.
Wes Morgan and Ian Breckin headed home corners before half-time and Southall headed in a second and then fired home from close range for his hat-trick.
Morgan headed home a sixth before Swindon's Jerel Ifil saw red. Trevor Benjamin pulled one back, only for Jack Lester to make it seven.
