Time Out saysThe four Marx Brothers as stowaways trying to bull their way through immigration by pretending to be Maurice Chevalier (each hopefully doing an impersonation to prove it), then crashing a Long Island society party to sow havoc. With Monkey Business, their first screen original, the team cast caution to the winds, helped by a perky script ('Tell me, has your grandfather's beard got any money?' - 'Money? Why it fell hair to a fortune') and some lunatic sight gags. Thelma Todd provides Groucho with his most delectable and intelligent foil.
