Huddersfield and Brentford shared the points after an eight-goal thriller.
Danny Ward notched an impressive quick-fire brace before Jeffrey Schlupp levelled the scores with two good finishes after poor defending.
Lee Novak smashed the Terriers back in front before home keeper Ian Bennett mis-kicked to give Lewis Grabban a tap-in for 3-3.
Ward set up Benik Afobe to put the hosts ahead for a third time only for Grabban to level from Schlupp's pass.
Huddersfield manager Lee Clark told BBC Radio Leeds:
"Not ideal but I've said to the players that it's just one of the those days at the office.
"Hopefully it's another wake-up call, which you always need now and then.
"We just have to look at it, dissect it, work with the players and make sure we don't do it next Saturday and onwards.
"I'm not going to criticise the players after 25 games unbeaten, we'll get back to where we were being a solid unit."
Brentford boss Nicky Forster told BBC London 94.9:
"I thought we were fantastic at today and carved them open at will at times, and they're a good team and we shouldn't forget that.
"It was a little bit too open at the other end for us but I thought we were well worthy of the point and possibly the three if I'm honest.
"I'd rather 4-4 than 0-0 as it shows the strikers are scoring, and they can take the confidence into the next game."
