*gimminy crickets is the standard non offensive expletive suitably used in place of holy references, such as "Dear god in Heaven, is lj ever fricking fast." or sexual innuendo, as in "Lj is performing better than an $1000 hooker..." or a combination of these links, as can be seen in such comments as "Baby! Lj is putting out like a catholic girl on a field trip." I could go on...
