Grover's back slaps

During the first decade of Sesame Street, a common feature of Kermit's Lectures was Grover's unwanted help. Grover would make his presence known as he strolls by in the background and taking notice of Kermit as he speaks to the audience. Grover would then run up to him screaming, "Hey, froggy baby!" and giving him a rather hard black slap, usually propelling Kermit forward. The gag became frequent enough that variations by Kermit were soon done.

Instances

• A 1969 sketch with a Grover-precursor features the earliest-known version of the gag, having the monster appear beside Kermit, saying "Hey there, frog!" and giving him a tough pat. The first sketch where the proto-Grover earns his name also features the gag.

• A 1970 appearance on The Ed Sullivan Show (featuring one of the earliest appearances of Grover, just following the finale of Season 1) has him yelling, "Hey, froggy!" and slapping him on the back.

• A Season 2 segment features Grover helping Herbert Birdsfoot demonstrate over and under. Before the lecture, Grover gives a hard slap on Herbert Birdsfoot's back. It causes Herbert to cough, making Grover think that he has a cold.

• Grover slaps Kermit's back at the beginning of a sketch about Heavy and Light.

• A Sesame Street News Flash segment on what makes people angry features a cameo by Grover. This time, Grover gives Kermit a slap on the back as he exits the scene.

• Appearing on Dinah! in 1977, Dinah Shore asks Kermit what he would like for his birthday, and Kermit asks that he not get hit by Grover as a greeting. This leads to Grover demonstrating the routine, and he asks Dinah how he could ever give up such a gesture of affection.

• In a Play with Me Sesame segment, Grover rushes up to Prairie Dawn yelling "Hey, Prairie baby!" and he gives her a slap in the back before he helps her sing the song "Beep." Grover does the same to Ernie in a separate segment.
