Previously I posted something about actors who have played two different characters on seinfeld:
* Jack Jarmal & the op in the Trip episode * George's girlfriend in the doodle, the girl who fires goerge in the accountant
well I found another actor who does a double take in seinfeld
In the Kiss hello episode the receptionist of the girl with the bad hair the one that say 'she is super' and 'i'm sorry we require 24 hours notice for cancelations. This actor also plays one of the clerks in the episode where Kramer goes to the bank in order to cash in on the offer of receiving one hundred bucks for the clerk/teller not saying hello, I think this is the invitations episode.
Also I found another error or inconsistency in one of the episodes, this time in 'the stranded'where Jerry and elaine are waiting for Kramer to pick them up from the party, look when both elaine and Jerry are sitting down on the couch talking to the owners of the house, in one shot Jerry is holding a book, then in another I think the book appears on the table, then in the next shot it is back in Jerry hands.
