Remember the "Us" concert series (because "all the money goes to US!")?
Van Halen's lead singer (David Lee Roth at that time) grabbed Opus and lifted him over his head, yelling "Let's rock!!" or something to that effect.
Opus was pointing and said, "OHH great... now they're burning the Porta-Potties".
Still gives me a belly-laugh. And there were so many more like that.
I remember the strips with Steve and Bill appearing before Tipper Gore's committee...Steve saying "Cooperation, Madame Committee Chairwoman, is our second name." And Bill in the same panel yelling, "SOLD MY SOUL TO ROCK N' ROLL! AACK!"
Trivia question...which company sponsored the one (and only) Boingers World Tour?
I seem to remember a series about the olive loaf vigilante. Opus was going around beating mimes to death with an olive loaf or something.
