Helium Radio Show

Tonight, I'm performing at helium with 3 other comedians for a small radio sponsored show. Its at Helium , a venue that I am very familiar with. The show however, I'm not so sure.
   I figured the three radio DJ's would open the show so I waited in the green room.  To my surprise, I was introduced as the host and MC, before the radio DJs even took the stage. I did not know what to do, so I rushed on stage a little frazzled and addressed the audience just like I would any other host job.
   Set went well, but about 10 minutes into my 15 minutes set, another comedian walked up the side of the stage and handed me a drink with a note. Obviously the note was the real reason for him to be there.
    The note basically said that I was supposed to introduce the three radio DJ's next instead of a comedian. But it startled me and caught me off guard, I ended up ending my set pretty abruptly because I thought the note was in a "get off stage now, you're fucking up" context. Was I supposed to introduce the three radio DJ's immediately? Have I been on stage for 10 minutes when I should have only been on for 1? A lot of thoughts went racing through my mind.
   I brought the three radio DJs up and even screwed up one of their names. Real classy. Luckily they played it off well, and besides the really awkward ending, my set was ok. Its just you remember the bad things.
    I felt real bad after that for a while. Then I listened to Andrew WK, smoked some weed, and felt much better.
