Gimpel was not exactly the brightest talmid of Yeshivas haKanoim. So, instead of learning, he was assigned to mishmar hashechuna, which meant yelling “Shygetz Aross” at anyone from an opposing community who dared enter the street on which the yeshiva was located.
Somehow, a Chabad mitzva tank managed to pick up poor Gimpel, and realizing he was not of very high intellectual capability, all they could do with him was to give him a loudspeaker and have him announce “We Want Moshiach Now” to get people’s attention.
The Yeshivas haKanoim crowd being what they are, they kidnapped him once again and set him back to mishmar hashechuna. This time, though, he was totally confused and spent his hapless days screaming “We want shygetz now! Moshiach aross!”
(Sadly, there are quite a few Gimpels out there, not all of inferior mental aptitude but all of whom are in essence yelling Moshiach aross).
