So we already know that chatzi maneh felafel is the gematria mashiach ben dovid.
(Anyone who says that gematrias dont work with non lashon hakodesh simply is incorrect, as the gemara does so on at least 2 occasions that I have seen, and I have not seen a lot.)
This proves that if we were to just eat more felafel moshiach would come, it also might prove that moshiach is ion fact a felafel sandwich (Though its a machlokes if a falafel is actually a sandwich ayin the debates over whether a hotdog is a sandwich)
