I got a laugh when Rene Auberjonois said wearing the Odo makeup felt a bit like having a cold all the time. I don't remember which video he said it in.
I don't know if I could handle wearing alien mask stuff. Small pieces? Okay. But I have trouble with those rubbery masks on Halloween. I'm not claustrophobic, but I hate feeling that sweaty stuff on my skin, eeew!
