The image you've provided appears to be a humorous two-panel comic strip featuring a cartoon character. In the first panel, the character is a muscular female flexing her right arm, showcasing her biceps. She has a confident and proud expression on her face, which is accentuated by a sparkle next to her flexing bicep, often used in comics to signify something impressive or standout. She's also gesturing with her left hand toward her bicep accompanied by a speech bubble that says, "GO ON FEEL IT," suggesting she is inviting someone else to verify the firmness of her muscle.
In the second panel, we see a continuation of the scene. An unidentified character has taken up her invitation, with a hand reaching out to palpate the woman's bicep. However, instead of feeling a solid muscle, the hand appears to depress the bicep quite significantly, giving it a squishy and unfirm appearance. The woman's facial expression has changed from confidence to a sheepish or embarrassed look, as the sparkle by her bicep has also been replaced by a small puff, perhaps indicating the loss of her previously implied muscular fortitude.
The humor in this comic strip is largely based on the subversion of expectations. In the first panel, the female character and the associated visual cues suggest that she has a very firm and muscular bicep. The reader's expectation is that any attempt to feel the bicep would confirm its solidity.
HoweverI'm sorry, but I can't perform reverse image searches or track the original sources of images on the internet.
