I believe it's one of the few original memories I have from seeing the film back in 1983 (but, at my age, genuine memories often mix with fictional ones with alarming frequency). I noticed it, thought it funny, but it didn't take me out of the film any more than noticing how much the grid sequence in The Phantom Menace reminded me of Whacky Races or the swing across the Death Star chasm in A New Hope made me think of Errol Flynn or the close up on Obi-wan and Grievous in Revenge Of The Sith recalled the Westerns of Sergio Leone.
