Something about Susan saying "yeah, dude" amuses me to no end.
By "more embarrassing results", Susan is, of course, referencing the fact that the TF gun doesn't change clothing. Also, it's not really all that dignified to get zapped by some weird green beam, is it? Awkward to do if zapping one's self, too.
I'm pretty sure I've initially forgotten Tedd's whisker-freckles with every appearance thus far in this storyline. I've caught it before uploading every time, but still. Those whisker-freckles are trolling me.
