I see the Promotion vs. thread, but there have been other moments of pure joy as a Reading fan, surely! Moments where you just completely lost your head out of the sheer ecstasy!
My picks would be:
Henderson's last minute winner at Peterborough
Doyle's goal at Leicester
Curo's goal at Brentford (can't find a link

Forster's goal at Wolves '03
Taking the lead against Derby on last day of relegation season (bit empty now, but at the time...)
Edit: Can't believe I forgot this!
