[Growltigger]

Cue loud blarting music, crashing of doors to the cantina kitchen, heavenly choirs of seraphim and cherubim, dancing girls, line dancing cowboys and Growltigga, clutching the red hot poker handcannon, backed up by the infintie hordes of Byzantine killer mongoose, clutching axes and wheeling the heavy artillery into position.....

I think the phrase commonly used is something along the lines of "come and have a go if you think your hard enough".

PS Dogscoff, glad someone (and an Englishman to boot) spotted the irony in my Last post. Nice to see educational standards are being maintained there on the south coast.
