Really classic. Look for the Smith and Dale clip at the bottom. And note how much different this verbal comedy is than Jack's (thus why he, Frank Fay, and others were really groundbreaking). You can kind of see the evolution from:
- Smith and Dale Dr. Kronkeit
- The Marx Bros Why a Duck
- Abbott and Costello Who's on First
- Nichols and May Operator routine
- Cheech and Chong Dave's not here man (OK, that was stretching a bit far)
The blocking character - frustrated patsy dynamic, although the patsy always has his ways of keeping his footing in the discussion (and sometimes they switch off roles). Jack could be considered a frustrated patsy, but I don't think of the rest of the cast as necessarily blocking characters--more colorful schtick characters.
